USAMade’s New Oval Sharktooth Chainrings

Whether you’re zipping along the fabulous singletrack or attacking that locals ride sprint, USAMade’s new Oval Sharktooth chainrings have a tooth count to match. Their newest rings are available in both GXP and BB30 SRAM direct mount and 110bcd Shimano asymmetric 4-bolt configurations, the latter with inner and outer rings for double road set ups. While pricing starts at just $23…

Also the rings are machined from 6061-T6 alloy and come with a limited lifetime warranty. The Shark Tooth design is combined with wide-narrow teeth chain retention on their direct-mount 1x rings, which they claim offers zero chain drops. The black ano is finished with a Teflon surface treatment for smoother, cleaner operation.

For GXP and BB30 direct mount, they offer 30/32/34 tooth options, all with 0mm offset. Use their 6mm adapter to space it out for long-spindle setups. For 110mm Shimano 4-Bolt they offer 34/36/38 tooth inner and  50/52/53 tooth outer chainrings. They also offer the same tooth counts in a 110bcd standard 5-bolt pattern for non-Shimano cranks.

Easton EC90 SL Carbon Crankset w/ BB86 /PF30 /BSA30 bottom brackets

2017 Easton EC90 SL Carbon Crankset

 




 

EC90 SL BB86 /PF30 /BSA30 Carbon Crankset

 

Easton Cycling recently unveiled their re-entry into the carbon market. It highlights the 2017 Easton Crankset synergy with their merger with RaceFace by sharing the Cinch chainring attachment design and composite arm construction. After all, if the Easton EC90 are anywhere near what the RaceFace Next have achieved, because they are among the lightest out there, so what a great place to get started. The EC90 weight falls at a mere 442 grams…

 

2017 Easton EC90 SL Carbon Double Chainring crankset

 

The EC90 setup comes with a new direct mount ring design that employs narrow/wide specifically tailored to road/cx/gravel applications. The individual tooth profile has moved from the traditional symmetrical shape to more directional specific design with the intention to create a positive chain roller engagement to help with EC90 chain retention, critical to prevent chain bounce over the roughest terrain.

All rings feature the Cinch Direct Mount System making a swap between ring sizes or even between double ring configurations a fast and simple procedure. Using the Cinch DM System also provides a significant weight savings by eliminating the material overlap and extra bolt hardware that is required for a traditional spider with chainring configuration.

2017 Easton EC90 SL narrow-wide 1x chainrings

  • The EC90 rings have 47mm chainline with the 129mm spindle, this is the optimal chainline for 135/142mm rear hub spacing which covers all road/CX disc bikes.
  • 47mm chainline gives full access to all gears on your rear cassette with efficient power transfer and minimal running noise.

The SL chainset don’t have to be paired with Easton’s bottom brackets, as they will generally work with any aftermarket 30mm BB, but some spacers may be required.

Beyond the EC90 SL, they believe Bottom Brackets are an essential part of the bicycle that is often overlooked and forgotten, and see the BB as another opportunity for performance gains and improved efficiency. Typically with any bearing there is a tradeoff between protecting the bearing internals for longevity and bearing seal drag which impact efficiency. For their new BB they developed a seal that achieves a very low level of seal drag while still retaining excellent protection qualities. With their in-house testing procedure where they essentially pour water into the side of the spinning bearings for an entire day non stop, and their new seal proved to have excellent contaminant exclusion.

They also use a new thinner low viscosity bearing grease and modified the grease fill to find the perfect balance between durability and minimized running friction. So if you’re going to run the best EC90 Crankset on the market, you should have the performance BB to back it up.

Shimano XT Level STePS E-bike Offroad MTB

Shimano XT Level STePS E-bike Offroad MTB

Shimano is making the jump to electrify mountain bikes as they have now developed a new trail-specific version of their STePS e-bike drivetrain that they are calling STePS MTB. The all new e-MTB components are designed to deliver XT-level fit and finish to get to riders serious about riding off-road, but who are looking to extend their range to explore farther from the trailhead. The new group is sure to spark some heated debate, especially in the states where trail access could potentially be at risk, but in Europe where e-bikes are seeing steady growth Shimano seems to have needed to get in the game, lest they risk being left behind. 

Shimano XT Level STePS E-bike Offroad MTB crankset

Like the urban STePS system, and the other systems from the likes of Bosch, Yamaha,Specialized, and other that came before them, the new STePS e-MTB group is simply a pedal-assist that adds to the power the rider puts into the pedals, and has an upper speed limit where it ceases to supply power. Shimano and others see this solution that will help riders travel farther without creating motor bikes that will be ripping down the trails at significantly higher speeds. The marketing hype goal is to somewhat level the playing field between riders at different fitness levels, so that they can enjoy a ride together.

The XT 8000-level spec means there will be a hollow forged crankset (above), with dual color finish to match an otherwise XT group out back. At the same time, a solid Deore level crank (below) will also be available to match a lower level spec. Both arms use the same electronics and a Hollowtech II bottom bracket setup. Chain rings will get XT profiles (in 34T or 38T) and an optional chainguide will be part of the overall kit that can either mount to a direct mount or to the drive unit itself.

Shimano XT Level STePS E-bike MTB motor

The new relatively light E8000 drive unit (yes, that’s a motor) was designed to be more compact that the E6000 urban version with the goal of producing bikes with shorter chainstays for better trail handling. It has an output of 70Nm or torque, and also claims to have a narrow 175mm Q-factor so you get the feeling of pedaling a normal mountain bike.

Powering the motor is an impact, vibration, and water-resistant 500Wh battery that has been specifically designed for off-road riding. The new downtube-mounted battery will be backwards compatible with the E6000 systems as well.

Shimano XT Level STePS E-bike Offroad shifter-computer

The entire system is then controlled by the left hand-mounted shifter that bears some similarities to Di2 shifters, and a computer/display that together let you cycle through its three assist modes: Eco, Trail, and Boost, plus the addition of a walking assist mode when even the e-MTB can get up the hills under your own power. A speed sensor attached to the rear wheel shuts power down at its speed limit.

The rest of the drivetrain components (rear derailleur, shifter, and chain) can be mixed with either 10 or 11 speed bits and either Di2 or mechanical shifting. STePS MTB itself is designed to communicate by Bluetooth with the Di2 E-tube setup to let the user customize settings and setup.

STePS MTB is projected to be available to consumers from October 2016, so we expect to see it get spec’ed on a number of e-bikes that will be seen debuted at the autumn tradeshows.

Shimano XT Di2 M8050 Mountain Bike Groupset Is Here w/ Wireless debut for all Di2!

Shimano XT Di2 groupset



Similar to how Shimano Di2 trickled down on the road, it now brings electronic shifting down to the a more affordable level for your mountain bike. And, just as Ultegra Di2 ushered in the new E-Tube and other technologies that improved upon the original, so too does the new XT Di2 M8050 groupset which brings a host of impressive new tech and features to their battery powered groups.

Shimano’s road product manager Dave Lawrence,  was on hand to describe how the new XT Di2 will improve the entire Di2 family. “We looked at electronic shifting and how that would change the ride experience. What we found was we could offer incredibly precise shifting. And the ergonomics were fantastic, too. Then we moved it into triathlon, but when we started using it in cyclocross is when it really took off. You had this precise shifting in the worst possible conditions.”

From there, it trickled down to Ultegra and a switch to their plug-and-play E-tube connections. That made remote shifters possible and really brought electronic shifting to the masses. Also the Dura Ace version put their electronic shifting below the weight of a mechanical group for the first time. All of these improvements then trickled down again to Ultegra, and then they took Di2 to their Alfine, Nexus and Steps pavement groups.

XT Di2

From there, it all combined to create the first digital mountain bike system, XTR Di2. And why did they do that?

“Di2 leaves behind some of the restrictions imposed by mechanical systems,” added Matt Robertson, Shimano’s mountain bike product manager. “Things like using cables to pull something and how to route the cables to make it work correctly. And it opened up new opportunities to combine shift and suspension functions operating off the same battery. Di2 improves rider momentum and efficiency, and it allows the drivetrain to react at the speed that you are reacting to your surroundings. Rider input leads to instant reaction from the bike. In short, Di2 lets people build a better mountain bike.”

That’s all well and good, but XTR Di2’s price put it outside the realm of most enthusiasts. The new XT Di2 will be more accessible, with a complete group price starting around $1,368 for a 1×11 setup, including brakes. It’ll also have better ergonomics, and it introduces all new wireless setup and data transmission features.

Shimano XT Di2 SW-M8050-R trigger shifter

XT Di2 still gets the independent adjustment of each button’s extension toward the grip. The bottom pad is a little larger than XTR, and the top pad is a little longer, making them easier to hit. XT’s button pads are also flatter, and felt much better. Two cost saving measures were limiting the number of clicks and using steel rather than titanium. XT’s levers have a single-click rather than XTR’s two-click design. They found that it simplified it a bit, and with Multi-Shift, the second click wasn’t as necessary as most riders quickly learned how long they needed to hold a lever down to shift a specific number of cogs.

Shimano XT Di2 RD-M8050 Rear Derailleur

The M8050 rear derailleur is Direct Mount compatible. Materials make up much of the rest of the cost savings. Functionally the units are the same as XTR Di2, and parts are interchangeable between the groups. In fact, while folks have been doing it for a while, Shimano’s finally starting to talk about using road Di2 drop bar shifters with mountain Di2 derailleurs (or vice versa). There were lots of NAHBS bikes doing just that, but until very recently, Shimano hasn’t really endorsed or even discussed such mashups. You’ll still need to use both front and rear mountain or front and rear road derailleurs, you can’t mix one from road and mountain on the same bike.

 

 

Shimano XT FC-M8000 1x11 crankset 2016

 

Non electrical groupset parts (cranks, brakes, cassette, chain, and pedals) all carry over from the recently updated XT 8000. They offer an 11-46 cassette for 1×11 systems, and either 11-40 or 11-42 cassettes for 2×11 systems. The chainrings carry over, too, but a new +/- tooth profile is coming soon, which is basically their version of a narrow wide.

 

Perhaps the biggest news to come out of the XT Di2 introduction is their new dual-band Bluetooth and ANT communication. Bluetooth compatibility now lets you set up, tune and change the shifting and functions with your smartphone or tablet. Available for iOS and Android, the E-tube app will let you customize and update the system on both smartphone and tablet, and the tablet app adds Error Check and Preset programs. Those last two are aimed more at bike shops than riders, but they’re there for all to use. You can also still do it with their E-tube PC software, too.

That dual transmitter will be built into the XT system information display, and a new dual transmission D-Fly that’ll add wireless updates to both road and mountain bike groups. XTR will soon get a new display, too.

The ANT signal is ANT Private, not ANT+, meaning it’s transmitting a closed protocol that carries gear data directly to an approved third party cycling computer (Garmin, Magellan, Wahoo and Pioneer are partners so far). So, you could choose to have a compatible computer show you that data if you choose not to use the Di2 display (or you’re using it on a road group that has no display).

 

Shimano XT di2 electronic wireless shifting

The trick to making all of that communication work is that you’ll also need either the new BT-DN110 battery or BM-DN100 battery mount. Both contain the brains that allow those smart functions that make the wireless display work. So if you wanted to add wireless function to an existing XTR group, you’ll need to upgrade to either the new battery or new battery mount. The new battery will replace the original battery, so going forward you should see OEM spec using the new one.

A new battery was necessary because they couldn’t fit any more memory into the original E-tube unit. As electronics continue to shrink, they could fit the necessary transistors and what not into the same size package to add functionality while maintaining the same level of battery power. So, the new battery is the same size as the old one, it just does more.

To recap, all of that new wireless communication will soon be available on all Di2 groups, road and mountain. Now that we’ve covered the new wireless setup, let’s jump back to the shifters. The XT shifters, through the app, can be set to control a Fox iCTD-equipped fork and/or shock.  So, using Shimano’s Synchro-Shift to automatically shift the front derailleur as you move up and down the cassette means you can use the left hand shifter to cycle through Open, Medium and Firm settings on your suspension. Or, what we think would be cool, is you could set the larger, lower thumb paddles to do downshifts on the left and upshifts on the right, then program the smaller top paddles to cycle the suspension settings.

The app will make it all incredibly easy thanks to a graphical interface and check box settings. Very cool, and very user friendly.

Wolf Tooth XT M8000 Ovalized Chainrings

Wolf Tooth XT M8000 Ovalized Chainrings



If you’re a fan of the elliptical chainring, Wolf Tooth Components should have your attention. Following in the pedal strokes of a number of previous Drop-Stop elliptical rings, WTC is introducing three more designs to continue to add compatibility.

For those that aren’t current on all of the chainring standards, there have been a number of new BCDs and bolt spacings introduced in recent years which makes the addition of new rings a necessity…

Shimano 110 BCD elliptical

For Shimano, WTC will be selling rings for both the new XT M8000 96mm BCD crank as well as 110 asymmetric 4 bolt road cranks. Other than their new fitting, the rings carry all of the same features and benefits of WTC elliptical rings with their patent pending Drop-Stop tooth profile and 7075-T6 aluminum construction. Using standard shape, the rings have a 10° ovality and 112° timing after Top Dead Center. The XT M8000 elliptical will sell for $64.95 in 30, 32, and 34t while the 110 4 bolt BCD ring will be a little more at $78.95 in 38, 40, and 42t.

RaceFace reverse dishPhotos c. WTC

Big news for fat bike riders is the addition of a reverse dish elliptical ring for RaceFace Cinch cranks. For a while now, fat bikers have been reversing the rings on Cinch cranks which offsets the dish towards the outside of the bike. This allows for proper chain line when running a crankset designed for a 170mm dropout bike on 190mm frame. Anyone who has pedaled the monstrous q-factor of a true 190mm (dropout) crank knows how big of deal this actually is.

Now, WTC is offering an elliptical chainring that is meant for this exact use. When used with a crank meant for a 170mm fat bike, the ring provides a 75mm chainline that is ideal for 190/197mm dropout frames. Selling for $69.95, the rings will be sold in 28, 30, and 32t options with 30t shipping now.

SRAM GX 1×11, 2×11, And 2×10 Drivetrain Options For 2016



 

Sram GX 1x11

 

What is the ideal mountain bike drivetrain? Well, that depends largely on who you ask, but it also varies greatly depending on what they’re riding. What works for an elite level athlete will likely not be the same system that works for your average weekend warrior. Throughout their most recent product releases, SRAM has invested heavily in the 1×11 concept which continues to gain traction. Lighter weight, no front derailleur, and a consistent chainring placement for bike engineers are all good things.

Realistically, having all the technology in the world won’t help you if your legs can’t push your bike up the next hill. While still banking on the 1×11 concept for a large portion of riders, SRAM is introducing an all new group that will have you ‘riding your way’ with their most affordable 1×11 group, plus an all new 2×11 drivetrain, and new 2×10 options as well…

Sram GX 1x11sp X-horizon rear derailleur -red

 

Depending on who you ask, the new GX 1×11 group should be one of the highlights of the new product line. Using almost all of the same technology as X1, X01, and XX1, GX(1?) brings 1x drivetrains to a new level of affordability.

Sram-Gearing-advantage

Regarding the gearing of 1x drivetrains, SRAM is quick to point out that they still offer the widest gear range in a head to head battle with Shimano. Of course, that wider gear range with the same number of gears will mean wider jumps between each individual cog. Ultimately the rider will have to decide what’s most important – short jumps making it easier to find the right gear for your cadence, or having the widest range of gearing possible.

Sram GX xg-1175 cassette

Admittedly, the star of the new GX 1x group would have to be the cassette. Don’t get us wrong, the SRAM X-Dome cassettes are works of art, but when you’re talking about a wear item, anything over $300 can be hard for a large portion of consumers to swallow. To us, that’s why the new XG-1150 Full Pin Cassette is so exciting. Sure, it’s over 80g heavier than the X1 cassette (394g claimed vs 313g actual) , but it retails for just $144. That’s less than half of the price of an X1 cassette. To get the price of the cassette down to a more affordable level, the XG-1150 10-42 relies on a full steel construction with each cog held in place with 123 total stainless steel pins. The cassette still uses an open design for excellent mud shedding and offers the same gear range as its higher end siblings, just in a price most of us can afford.

Considering a GX 1x group can be retrofitted for just $302 for the shifter, rear derailleur, and wide range cassette, or $573 for the entire group, we expect to see a lot more of SRAM 1x drivetrains at the trail head. For reference, the cassette alone for the X1 group just one model up sells for $313. Other than using a SRAM PC-X1 chain, the GX 1x group includes all of the parts to make up a complete drivetrain including a fixed spider and removable spider crankset.

Inter-compatible with other SRAM 1x groups, the Full Pin cassette still utilizes the SRAM XD cassette body, and the cranksets will have Boost 148 compatible options.

The other really big news is the introduction of a 2×11 drivetrain that utilizes the SRAM wide range cassette. That cassette part is key – it required a completely revised rear derailleur to be able to handle the chainwrap and capacity, but it also provides some of the widest range mountain bike gearing available. Shimano’s 3×11 XTR drivetrain (22-30-40 x 11-40) is missing from the chart, but you get the picture. If SRAM’s 1x drivetrains don’t offer a wide enough gear range, the new GX 2×11 should have you covered.

In order to make the 2×11 drivetrain work with the current 10-42 cassette, the rear derailleur had to move away from the X-horizon design in favor of a more traditional slant parallelogram. Still using their X-Actuation 11 speed shift indexing, the derailleur uses a new Type 3 Roller Bearing Clutch and continues the use of Cage Lock.

Sram GX trigger shifter 11sp red

 

With the addition of 2×11, comes SRAM’s first left hand 11 speed trigger shifter which is a dedicated 2x system. You may have thought you had seen the last of SRAM front derailleurs (at least for 11 speed), but there it is. An X-Glide, X-Actuation front derailleur. Initially, GX 2×11 cranksets will only be available with a 36-24 gearing but that will probably change in the future.

Finally, there is the new GX 2×10 group. Essentially a replacement of SRAM x7 (assuming GX 2×11 is a replacement for X9), GX 2×10 gets a facelift over the previous generation and a few new tweaks. Relying on the current SRAM PG-1050 and PG-1030 cassettes, the GX 2×10 will not benefit from the wide range of the 11 speed cousins, but this is clearly the most budget friendly option in the group.

Wheels Manufacturing BB30 And PF30 w/ ZERØ Ceramic Bearing



 

Time to Turn Up the ZERØ Ceramic Burner On the Local Singletrack!

Wheels Manufacturing BB30 And PF30 w ZERØ Ceramic Bearing-black

Technically these have been available direct from Wheels Manufacturing for about eight months now, offered in what they’ve called a “soft launch”, but they’re making their formal introduction at QBP’s Frost Bike this week. This means they’re going prime time with broader distribution, and as their reps show them off in below freezing temps, the story of what makes the Zero ceramic bearings special will seem right at home.

Using solid ceramic bearings, the races are cryogenically frozen to make them ultra hard. That increases the smoothness and durability, and then they swap in a single-lip seal rather than the usual dual lip seal to further reduce drag. Here’s the nuts and bolts of it…

Wheels Manufacturing BB30 And PF30 w ZERØ Ceramic Bearing-red

The bearings are Grade 3, which they say are the rounded balls you can get unless you’re building for the military. The real secret sauce is the races, which are treated with a black oxide coating, reground to a mirror finish and then cryogenically treated at -300ºF. This realigns the crystalline structure of the metal, making it incredibly hard. This hardness helps it hold up to the ceramic balls’ hardness, thus increasing the lifespan of the entire assembly.

The bottom bracket design itself uses their threaded shell, which pulls both sides into place in perfect alignment, boosting the performance even further. The Zero bearings be available in PF30 Outboard, BB30 Outboard, standard PF30, BB86/92, and Standard BSA BB. This includes the PF30-to-24 and 24/22 designs, allowing Shimano and SRAM GXP spindles to spin freely on PFBB30 frames. Retail is $175.

OneUp Components XTR M9000 11- Speed Narrow Wide Chainrings



 

 

Oneup Components XTR M9000 11- Speed Narrow Wide Chainrings

Latest OneUp XTR M9000 Narrow Wide Goods!

 

 

With a planned launch later this month, OneUp Component’s showing of their new narrow-wide chainrings for Shimano XTR M9000 came a bit early following this morning’s announcement from competitor Wolf Tooth. Made from the same 7075-T6 alloy as their other rings, these are anodized to color match the new XTR group. They’re made using the 96mm BCD and asymmetric bolt pattern of the new XTR group, too.

Beyond the tooth profile and color, the hardware is what makes OneUp’s different, as it comes with M9 bolt hardware that threads directly into the chainring. That’s compared to the M7 bolts that come stock with the XTR cranks, and the number refers to the bolt diameter (so, 9mm versus 7mm).

The OneUp product designers, have stated this larger diameter fills the hole in spider instead of relying on the alloy nuts used with Shimano’s rings, so it gives the bolts better strength and pulling/holding power. It’s also lighter, saving a claimed 35g over the stock 1x ring.

Weights are in the 40g to 50g range, and tooth count options are 30, 32 and 34 for now. If demand dictates, they’ll go for a XTR 36. While these XTR alternates are available below for $65 each, that includes all the hardware.

Claimed weights for the XTR setup:
30T – 43g
32T – 48g
34T – 57g

Sram XX1 Stealth Black With Carbon Crank Boots

 

Sram XX1 Stealth Black 11-speed cranks

Since black is the new black, SRAM has gone stealth with the XX1 Black group. Formerly only available with bright red logos, and a few other colors as OEM options for complete bike makers, the new group color is set to make it look better no matter what color frame or anodized Chris King headset you choose for your ultra high-end ride.

Also incorporating the new X-SYNC Direct Mount Chainring, the XX1 stealth group brings the newest of what SRAM has to offer, along with some nice new accessory additions. Take a look inside to see the other components and new small parts…

Sram XX1 Stealth Black trigger shifter

There are no mechanical changes (aside from using a different existing chainring on the crank) to any of the XX1 group’s parts, it is still the industry-leading 1×11 pioneer that has changed so many of our rides for the better.

Sram XX1 Stealth Black 1x11 derailleur

The XX1 group consists of an XX1 Crankset with X-SYNC Direct Mount Chainring ($456 for GXP, $488 for BB30), XX1 Rear Derailleur ($326), XX1 Trigger Shifter ($183), XG-1199 X-Dome Cassette  and PC-XX1 Chain. The cassette and the chain are the only items not getting any cosmetic treatment, as their siblings in the X01 family area already blacked out, and the distinctive champagne finish of the cassette is both a performance and visual difference for the higher-end cassette.

 

SRAM did not release new pricing on the chain and cassette since they are unchanged from the original XX1 group. The cassette retails for $425 and the chain for $63.

 

1×11 is completely changing the industry, and even allowing some bike manufacturers to be more creative with frame design being only compatible with a single front chainring. However, most manufacturers are still insuring the most choice for their customers, and designing bikes with front derailleurs in mind. If you have one of those frames, this High Direct Mount Front Derailleur Cover ($15) from Sram should hide that mounting point, and match the rest of the group nicely.

SRAM carbon crank-arm cover-boots

Race Face has offered rubber boots as a stock item with their cranks for years, even available in a rainbow of colors, SRAM’s starting out with all black to match the new stealth group. If you haven’t heard of these, they cover the ends of expensive carbon cranks so rock gardens don’t eat your expensive investment for lunchThey are quite simple, but make a huge difference as the boots are torn up, the cranks are still fine. SRAM simply calls them the Carbon Crank Boot, and they are $10.

New SRAM Direct-Mount X-Sync Chainrings




SRAM Direct-Mount X-Sync XX1 Chainrings

SRAM LIGHTENS 1X GROUPS W/ NEW DIRECT-MOUNT X-SYNC RINGS

Maybe prompted by other third party chainrings that are lighter, and the popularity of Race Face’s CINCH 1x rings, SRAM has stepped it up to take advantage of the weight savings to be had by designing a direct mount chainring setup. SRAM actually already had it in place, but until now it’s been used to hold the spider, thus making their X-Sync XX1, X01, and X1 rings configured with a two piece design.

Fortunately the updated X-Sync drops that past generations two piece design to save weight, and it opens up both smaller and bigger tooth counts. You can now get an X-Sync ring with just 26 teeth or up to as big as 40 teeth, w/ all the  even increments in between now accounted for. The other interesting topic to take note of is compatibility. They not only fit your XX1, X01 and X1 1400 cranksets, but with the X0, and X9 crank arms from the past few years… while you won’t be able to retrofit the X-Sync to a standard XX model.

SRAM Direct-Mount X-Sync spiderless Chainring

SRAM has stated these are specifically designed for the ring offset of their 1x crank arms, but that the direct mount interface will fit modern X0 and X9 crank arms. So it sounds like you’ll just need to pay attention to offset to ensure proper chain line and tire/frame clearance. They also have different offsets depending on whether you’re using GXP or BB30 cranks.

Like the originals, the new X-Sync is fully CNC’d alloy, engineered in Germany and use their X-Sync wide/narrow tooth profiles to keep the chain in place and help shed mud. They’ll be available for both GXP and BB30 spindle versions. Weight savings over the X-Sync spidered versions range from about 25 to 50 grams, and the claimed weights are listed below.

GXPBB30
26T61g52g
28T66g58g
30T68g61g
32T71g66g
34T76g71g
36T91g82g
38T101g94g
40T119g106g

Perhaps the only tradeoff is that you’ll have to remove your drive-side crank arm to change the rings, something you don’t need to do with the two-piece design. So, if you’re constantly changing rings to suit conditions, it might be worth hanging on to your 2-piece setup.

SRAM Direct-Mount X-Sync Chainrings

The 30, 32 and 34 tooth counts for the X-Sync will all be available soon, while all the other sizes will follow in April 2015. Retail is $99 / €88 / £75.

Tune Blackfoot Carbon MTB Cranks



 

tune king fat kong fat-bike hub

Tune has been hard at work to not only make the fat bike industry a little less hefty, by designing a new 190mm rear and 150mm front hub option. They have dubbed them the Fat Kong at 170mm for the rear and a 135/142mm Fat King front. But Tune has also updated their regular rear hubs by employing the lighter weight Skyline freehub body that’s drilled out, all without raising the price tag.

They also brought several new fat bike thru axles and skewers to go with the new hubs, plus plenty of other lightweight Blackfoot goods… to the 2014 Eurobike show.

 

tune king fat-kong thru-axle

New thru axles and AC skewers for fat bikes utilize a new, larger diameter carbon lever setup.

Wolf Tooth Components Drop-stop XTR M985 and SRAM Direct Mount Chainrings



 

wolf tooth M985 narrow wide chainrings

 

Narrow Wide

For the small bicycle parts manufacture dubbed Wolf Tooth Components who are based out of Minneapolis, things are looking mighty fine due in part to their ability to be ahead of the curve. They were ultimately able to position their design and engineering near the front of the drop-stop chainrings, and single ring revolution for anti dropping rings that are currently upon us that will open up the door for compatibility with other cranks besides the wonderful XX1, they are milling out the goods.

They have also been hard at work bringing in a new marketing and pr man to head up the sales and sponsorship, along with a newly updated website to now call home. They will now provide free shipping on all orders, which includes international sales as well, with new lower pricing to boot. As we speak, the Shimano sponsored Nicola Rohbach, along with Lukas  and Mathias Flückiger who are a few who are praising the WTC chainrings on their mountain bikes racing the World Cup cross country scene  – thus speaking volumes for some of the best racers on the planet to be utilizing your mtb parts even though being sponsored by the big hitter Japanese brand.

 

Shown below is the configuration for what the SRAM DM rings are all about along with the drop-stop Shimano M985 shown at the bottom of the article.

 

wolf tooth DM32-with-bash

The SRAM DM version will be available in two sizes of both 32 and 34T, and reported to have several additional sizes available in the upcoming weeks. They will also attach directly to the splined interface of the crankset and provide additional bolt holes located on the ring itself for to combine their very own bash guard. As with many cranksets’ these days they are not a traditional BCD, so if you’re needing to employ a bash guard, they also have them available for purchase at the new website.

wolf tooth M985-anodized

And for the XTR M985 setup that utilizes a 88 BCD 4-bolt setup they currently have both 36 and 38T diameters, with additional smaller sizes that will also be available the coming weeks as well.

 

SRAM/ Truvativ XO 3.3 GXP Crankset



 

 

Truvativ XO 3.3 GXP 3x10 chainset

When you need plenty of gear options for any style of trail system. There is nothing better than the triple chain ring setup for a ton of diverse choices. And the SRAM/ Truvativ XO Silver 3×10 -Speed Chainset will provide those gear options with panache and style. They have truly designed it to be a whatever mountain crankset. This is SRAMs’ Silver Edition that is very close to being identical to the standard XO setup, but they nicely polished small bits of the chain rings to take you back in time to some of the original mountain bikes of yesteryear.

The newest Chainset model though utilizes carbon fiber to manufacture the arms out of. There is only a small bit off aluminum used where you thread your pedal into the end of the arm.

Truvativ have also used aluminum for the manufacturing of the 104/64 BCD spider for diversity with different chain ring options. The alloy spider setup is nice that it’s removable to change out your gearing if you don’t need the triple combination anymore and would prefer to set it up as a double chainring setup without buying a whole new set for the mtb.

SRAM has also put a fair amount of work into their chain rings for 2013 with their latest X-glide program. The XO rings have actually been re-engineered to change th makeup of how many shift ramps, pins, along with cut outs that exist on the outer and middle rings. So they added to the setup to make the smoothest and fastest up shifts possible. So now you can almost nearly get the chain to lift on the outer chain ring almost the entire revolution of the crank arm.

SRAM also coated the carbon fiber Truvativ XO Silver 3.3 Crankarms with a clear coating and a nice touch with a mix of Black anodizing and polished bits like the 7075 alloy chain rings and spider. They also come with two lengths for the arms available at 175 or 170mm that feature 22, 33, 44 tooth rings.

 

  • The XO Mountain Bike Carbon Crankarms are very lightweight and super stiff with amazing durability.
  • 3×10 chainset utilize the X-Glide shifting technology
  • New chain ring options of 22/33/44 tooth
  • Newly updated design for GXP Bottom Bracket System that features new two-stage Gutter Seal Technology

Truvativ X0 2.2 GXP Crankset



 

 

sram xo 2.2 crankset

Truvativ has utilized carbon fiber for the arms of the X0 2.2 Crankset similar to their upper end XX version, but they differ in a couple of ways. The first item that is different on the two cranks is the aluminum spine that connects the threads for the pedal axle connection. Some how SRAM designers were able to figured out a way to engineer a foam core inside the carbon outer layer in replace of it. Their are no worries though in regards to a weaker setup, because their ultimate goal for the X0 crank was to make them easily withstand all the abuse of trail/all-mountain arena.The other change between the two mtb versions was the use of an alloy spider on the X0 2.2 chainset instead of carbon fiber that dons the XX. Although it’s several grams heavier, their design is great because it will enable you to opt for different gearing such as a 3-by setup, or a 2×10 setup simply by removing the spider. It comes though setup from the factory as a 2×10 system.

SRAM has also optimized the bolt circle pattern along with the bolt circle diameters as well to minimize any chainring flex. At the same time they also changed up the shift ramps to be two-by-specific along with the pins on the outer ring. It has become pretty standard with chainrings these days to utilize two drop pins and two shift ramps for the chain to either drop or lift quicker while shifting under pressure. This only gives the chain two opportunities to shift during each crank revolution, thus leaving two dead spots, making shifting iffy sometimes. But the new X0 big ring design makes perfect shifts for nearly a full revolution. It has been termed the X-Glide system. The other improvement is simply because mechanically you now only have two rings, for far less front derailleur fuss.

These SRAM Truvativ X0 2.2 Cranks come with a GXP bottom bracket and durable Carbon arms that are clear coated and have pre-installed Black ano 7075 T6 alloy chain rings and spider, colors available are shown below. The version also comes with four different options for chain ring setups listed below.

SRAM XX Carbon MTB 2×10 Crankset

sram xx 10-speed crankset

 

SRAM pushed the gram scale to a mere 637 grams for the new XX Crankset (with the 156mm Q-factor model), yet the creative designers were still able to deliver off the charts durability and performance with there being no penalty on race day with unwanted weight on your 29r race bike. They were the first manufacture in the mountain bike industry to not only build a double specific crankset for mountain bikes but with a complete XX group to match and run with it – proudly designed with some of the most hi-tech material science in the world.SRAM also opted to completely rework the configuration of the XX Truvativ chain-ring-set by building them over sized with 6mm 7075 aluminum in the CNC machine from alloy blanks— they ended up being a full 2mm thicker than any other chain ring in the MTB industry. All of this makes for unparalleled stiffness because they also made the Bolt Circle Diameter bigger thus placing the bolts that much closer to the outer edge of the chain ring to support it that much more. There are two different Truvativ XX models available, the XX 156mm Q factor version and a 162mm Q-factor model as well. They both provide some of most efficient chain-line numbers that the mtb industry has ever seen. Upper level science in action at its finest.

  • Advanced Technology

 

  • Composite arms are super lightweight and extremely stiff with amazing durability.
  • Specific Beveled design to maximize heal and shoe clearance
  • 2-piece insert-molded carbon fiber construction, to further lighten the model and make it stiffer
  • 2×10 Aluminum T6 rings utilize the X-Glide shifting technology
  • New crankset chain ring options are 28/42t and 26/39t
  • Newly updated design for GXP Bottom Bracket System that features new two-stage Gutter Seal Technology
  • Requires the following Bottom Bracket configuration: GXP
  • GXP bottom bracket not included
  • The measurement on the scale for the 166mm Q-factor model is 653 grams
  • Total Weight for the SRAM XX Crankset is 637 grams for the 156mm model

SRAM XO DH Crankset (Single Ring Application)



 

 

SRAM XO DH crank arms

Unfortunately over the years down-hill-specific mountain bike drive-trains have not just been incredibly durable and stiff but they served as perfect boat anchors for that Saturday morning outing to go fishing. But thankfully SRAM was poised to change the heavyweight madness with the Truvativ XO DH Set and yet keep the tough and tumble reputation intact. The key reason designers were able to lose a fair amount of weight on the downhill version was the implementation of carbon fiber for the arms similar to their XC brethren. You will literally save hundreds of grams with the XO over the comparable Holzfeller set, which works out to be impressive lower rotational weight on the race bike thus enabling you to brake into the podium zone on the timer.The Truvativ designers some how figured out how to utilize a rigid foam element for the core of the arm that is every bit as stiff as the metal counterpart, they have then wrapped it all up to conceal and protect the rigid foam in a burly composite outer skin. All to get the best possible strength to weight ratio. They have also integrated 7005 T6 into the end of the arms to accept the threaded interface of a pedal axle. The ultimate goal here for Truvativ was to make their XO DH components worthy enough to undertake all the punishment dished out on the World Cup racing circuit.

The SRAM XO DH MTB Crankset utilizes a durable clear coating for the carbon fiber arms. They have also anodized the 7075-T6 alloy chain-ring and spider Stealth Black. The version was also designed with a standard bolt circle of 104mm with chain ring sizes shown below.

  • Advanced Technology

 

  • Composite arms are very lightweight and super stiff with amazing durability.
  • Setup is a single ring such as a 1 X 10 configuration
  • Arm lengths are available in 175, 170, and 165mm
  • Chain ring options are 34, 36, or 38t
  • Utilizes the following Bottom Bracket configuration: GXP
  • The GXP Bottom Bracket is not included

2014 Truvativ XO DH GXP Single Crankset



 

 

truvativ xo dh gxp single crankset 2014

model: Uses Truvativ GXP Bottom Bracket

TWO PRIORITIES 1. Trail. 2. Fun.

With Srams’ inclusion of Truvativ XX for mountain bikes, they were first able to make double cranks a reality. The key ingredient was the (new back then) wider ranged 11/36 tooth 10-speed cassette. They followed suit as well with designing an applicable 2 speed front shifter and front derailleur. Which has since then made it’s way along so that 1×10 and eleven speed cogs could get the component trickle down effect to lower groups that happens so much in the cycling industry. So for 2014 we now have the XO DH GXP Single Cranks scoring from the ground work of the XX sibling, having the same simplicity and performance but with a bit lower price total. Instead of using carbon fiber for both the spider and crank arm, Truvativ applied a polished black anodized 7075-t6 aluminum spider on the XO model. Yes, the higher-end full carbon fiber crankset is a couple of grams lighter weight, but with this XO version they have really found great high performance point at a bit lower price number. The Truvativ XO also comes with an innovative style bottom bracket, noted below.

These Truvativ GXP bottom brackets are different — and better. The other BB designs rely on some sort of side-load on the bearings to eliminate the play, which causes premature bearing wear. This Truvativ DH system shown here has the left bearing placed in between left arm and the spindle which then allows the bearing on the drive-side to float axially on the spindle. Thus requires no side-loading of the bearings during installment and adjustment. Also making the installation and setup for the Truvativ system a lot simpler. This particular system also uses two bike-specific cartridge bearings along with 8 total seals to ensure a long-lasting life span and a smooth pedal stroke. Truvativ have also designed a new Gutter seal system for it that uses two different stages to direct any contaminates away and giving the bearings a longer lifespan as well. This new Gutter Seal setup reduces the friction as well by 35% over the current b.b. version. They also made the grooves for installation a bit deeper to apply torque easier on the adapter cups. This design has reduced 15 grams from their past years bottom bracket design.”

The Truvativ XO DH Crankset has clear coated carbon fiber arms with a Black anodized 7075-T6 aluminum spider and chain ring. They have employed a standard 104mm bolt circle that is available with either a 34, 36, or 38t chain ring for options. And it comes in three different crankarm lengths — 165, 170, and 175mm. You also have the option to select the bottom bracket/spindle width as well, see the purchase link below for more details..

 

 

  • New Truvativ Carbon arms are super stiff and light weight with incredible endurance durability.
  • Single chain ring sizes available are 34, 36, 38t

Truvativ X9 2.2 Crankset w/ GXP And BB30 Options



 

 

truvativ x9 bb30 2.2 cranks-white
model: GXP or BB30

TWO PRIORITIES 1. Trail. 2. Fun.

With Srams’ inclusion of  XX for mountain bikes, they were finally able to make double cranks a reality. The key ingredient was the (new back then) wider ranged 11/36 10-speed cogset. They also followed suit with an applicable 2 speed front shifter and derailleur. Which has since then made it so that 2×10 could get the component trickle down effect to lower groups that happens so much in the cycling industry. So here we have the Truvativ X9 2.2 Crankset scoring from the ground work of the XX brethren, same simplicity and performance but with a much lower price tag. Instead of carbon fiber, they used their hollow forging technique to put the X9 at an applicable performance/value criteria. Yes, the carbon higher-end models are a couple of grams lighter weight, but with such a big difference in cost really doesn’t make them comparable to this X9 version.

The highly refined GXP bottom brackets are different — and better. The other BB designs rely on some sort of side-load on the bearings to eliminate the play, which causes premature bearing wear. The system has the left bearing placed in between left arm and the spindle which then allows the bearing on the drive-side to float axially on the spindle. Thus requires no side-loading of the bearings during installment and adjustment. Also making the installation and setup a lot simpler.

Truvativ X9 bb30/gxp 3.3 crankset

model: utilizes the Gutter Seal Bottom Bracket

TWO PRIORITIES 1. Trail. 2. Fun.

Being one of their most popular models the Truvativ X9 3.3 Crankset is adorned and loved by everyone in the mountain bike scene from all day epic riders who climb huge amounts of vertical to simple weekend rippers enjoying the scenery. The new model from SRAM provides a nice balance between three key priorities, to be impressively stiff, long term durability and lower overall weight. They also have been recently working on a new development called the X-glide chain ring system which is very stiff and were designed to shift faster, along with being extremely predictable no matter what circumstance or condition you put them through, which is ultimately what makes them so popular. These tough but yet lightweight X9 cranks are all set to take on whatever endeavor you must face.

They have also set up the X9 3.3 model with a bottom bracket that utilizes the newest Gutter Seal technology. This design not only makes the bearings last longer but it also reduced the spindle friction by a whopping 35% over their past bottom bracket design of yesteryear. The designers also changed the grooves for installation rings by making the grooves slightly deeper for easier installation of the adapter cups. Their new engineering of the bottom bracket design also shed nearly 20 grams from last years BB model.

Rotor Q Ring XTR 970 Set



 

 

rotor 970 q-rings

Great news for Shimano XTR crank owners who thought they were limited to a couple of options to replace their chain rings. The new elliptical chain ring technology is now available with the MTB Triple Q-Ring 970 models which give you a great option for replacement. The XTR 970 crank utilizes a relatively standard 4-bolt 104/64 BCD pattern, but the dimensions from the rest of their mountain bike component lineup differ greatly. So the new rings were developed specific for their cranks only, or other manufactures that utilize the 104/64mm four-bolt setup as well.

As engineers Rotor figured out that at the bottom and top of the pedal stroke their are actually weak spots with most bike riders out there. So they developed a subtle oval shape for their rings to smooth out the pedal stroke through those two dead spots and to also take advantage of that natural power zone where the oval is located. They have several mounting holes to maximize this effect for all the different styles of pedalers out there.

They have also designed the chain rings for the best possible durability out of hard anodized 7075 alloy the gets milled with a CNC machine along with special shift enhancing details like ramps and pins and ramps to make them shift precise and fast. The black ano finish is the only color available. The Rotor outer ring size is a 44t, middle has 33t, and the inner has 23t. Total Weight for all three chainrings is 133 grams.

Rotor 3D 2×10 Double Crankset



 

 

rotor 3d 2x10 crankset

 

model: 2×10 ring setup/ rings not included

TWO PRIORITIES 1. Trail. 2. Fun.

This Rotor 3D setup is the 2×10 MTB model which utilizes two chain rings, they have developed the system to work nicely with a mixture of different front shifters. The advantage being, no more gear redundancy like what’s on a triple crankset. You are able to optimize the two rings to work perfectly with better and tighter chain line with a narrow q-factor of only 163mm. It’s also far less complicated and lighter weight to boot.

Rotor finished things off with the anodized color black for the new 3D Double that was also developed with three different options for arm lengths — 175, 172.5, and the 170mm. Their machined aluminum spider works with 5-hole 110/74mm chain rings. The chainrings are sold separately and may be purchase at the link below as well. This version can also be used with all 24mm external bearing BB systems that are designed to Shimano specifications. The 3D set only weighs a mere 543 grams.

The Euro company THM Carbone has pushed their development of high-end lightweight carbon items to the dirt side of things. Their newest Clavicula M3 mtb cranks utilize the same carbon layup and design as the THM Carbone road cranks but have a dirt oriented BCD/spider with four options for sizes. Off topic on the great looking item shown above but there are some pictures below as well of their new tapered steerer carbon fork, that was released at Eurobike as well. This is their first tapered carbon fork. You may have noticed around, any road bike that used their super light fork has always been with a straight steerer. But THM is trying to change things up slowly to modern times,  only an 1/8th inch at a time.  Pictures of their Clavicula M3 mountain bike specific items along with a sweet looking tapered fork are shown below…

Carbon-Ti has designed some new one-by — specific chain-rings that replace the crank’s standard spider for the Cannondale Hollowgram SL and SI cranks, the SRAM X0/X9/X7 cranksets, and the Specialized carbon cranks. They are called the X-Monoring Titanium single chain-rings.The tooth sizes available are 32/33/34/35/ and 36, which will be the perfect market for 29er bikes w/ one x systems, and they are also compatible with any of the 10 or 11-speed models on the trail. By changing out the spider, you will be subtracting some more grams, as well as adding a far more durable titanium chainring. The pricing and weights haven’t been reported just yet.

Olympic success along with Enduro Success as well for the 2013 SRAM XX1 Groupset

 

Now that mountain bike cog sets have been growing to bigger and bigger gear ranges than ever thought possible, the concept of single-chainring setups have been recently growing ten-fold in popularity numbers. By the simplicity of employing one single front ring means less shifting hassles, fewer dropped chains, along with better tire clearance and increased opportunities for all the newest innovative suspension designs popping up across the globe.

By knowing the evolution of dedicated drivetrains for mountain bikes, SRAM has pulled out all the stops with its 11-speed specific, single chainring groupset, dubbed the XX1.
SRAM details of new XX1 11-speed mountain bike drivetrain

SRAM XX1 is a full redesign of the whole 10-speed package, and all its components are incompatible with any existing groups.  They began with the update on the cranks with a specially designed single-chainring that does not need a device for chain retention, and they turned to the back with a new clutch-equipped, rear derailleur and a monster 10-42 cog set that requires its own dedicated freehub body.  Availability and cost will be October 2012, at $1449.00. You will also need to purchase a freehub body from DT Swiss to make the X1 cassette compatible with your rear wheel.

Developed for the best possible control of the chain, each tooth is precisely CNC-machined to support the SRAM XX1 chain’s outer and inner links perfectly. They have six chain rings available, 28-30-32-34-36-38 to give you options for your gear range to match your riding area, wheel size and pedaling style. The chain rings fit a single spider—allowing you to change out the rings without having to remove the carbon crank arm.

XX1 X-Horizon Rear derailleur/Sale Priced: $221.35

This new 11-speed X-Horizon rear derailleur is designed with a “horizontal parallelogram” and pulley offset, this keeps the chain gap constant across all 11 cogs, giving precise , fast shifts. By limiting all movement to the horizontal axis, this design is faster, reduces shift force and stops any ghost shifting. SRAM’s new roller bearing clutch technology reduces bounce and chain slap, while the derailleur’s Cage Lock system makes wheel removal and installation super easy.

SRAM XX1 Shifters

To complete the drivetrain Groupset the shifting is done via a dedicated thumb shifter or a Grip shift unit. They updated the Gripshifter to twist on ball bearings for increased durability and smoothness, with a metal indexing system. The thumb shifter is MatchMaker compatible with all the other brakes and accessories they design in house.

But when I saw the price and specs on the e.thirteen I bought it. I am running a Race Face single speed ring with MRP bb mounted 1.x guide and its great. The 30mm spindle with polygon interface translates to a very solid feeling set-up, I’ll use it on future builds, can’t be beat for the price.
