CCX40 Wheels w/ disc hubs
The Florida-based startup Alto Velo debuted their prototypes at Interbike with a disc brake version, with hopes to have them out early this year. That timeline came and went, but now, finally here.
Those design changes over the past year were done to ensure that their disc brake hub was good for anyone that needed a disc brake hub, regardless of discipline…
The CCX40 above and top, uses a custom 40mm deep carbon fiber rim. They kept their interchangeable axle design that lets you change out from QR to 12mm or 15mm thru axles in less than a minute. Each axle type does require a specific axle as opposed to end caps and spacers – it’s replacing one part with another single part, all of which are available separately.
The front hub uses the oversized flange on the non-drive side to make up for the offset required to make room for the disc brake rotor. Their testing showed that the widest offset and tallest flange isn’t necessarily the best solution because of what it does to spoke tension, and it’s doubly challenging to make a really good front disc brake wheel because there’s less width to play with. So, they did a lot of testing to balance ride quality with lateral stiffness at the right point. The result is an almost equal tension from left to right, which they say combines with their ultra-precise internals to make for a very smooth, balanced and strong setup.
The AX26 is the alloy rim option (and only tubeless ready option) with disc brakes. The alloy models are tubeless ready, and they’re made by another company in Jacksonville, FL (just up the road from Alto Velo’s HQ). It’s a custom drilled version of their 26mm deep Aileron.
Anytime they made changes to the hub, they had to change the rim, because the UD fibers in the carbon are all specific to the bracing angle of the spoke and the lacing pattern. So every time they made a change, they wanted to see it proven on the computer but also in real life. In true engineering fashion, they overanalyzed everything causing them to be six months late.
The CCX56 offers a deeper 56mm carbon fiber option for aero pursuits. The carbon models are made by one of the top Asian suppliers using Alto Velo’s own molds and design, which is necessary to work with their unique spoke angles. These are not officially tubeless ready yet (they’re working on it), but they’re using a new multi-angle drilling pattern to match both the bracing and lacing angles to have exactly linear placement of the spoke – there’s no bending tension or kinks in the spokes. That’s why they really strongly recommend buying a complete from them rather than just the hubs for your own custom build.
Weights are lower than they expected, with all of the gram here, gram there trimming helping shave 50-60g of comparable hubs from competitors. The rear is 270g and front is 114g. Complete wheelset weights and specs are:
AX26 claimed weights are 707g front, 878g rear.
The carbon options weigh in at (claimed):
- CCX40 Clincher – 693g F / 873g R
- CTX40 Tubular – 591g F / 771g R
- CCX56 Clincher – 750g F / 926g R
- CTX56 Tubular – 598g F / 774g R
All are laced 24 front (2x/2x) and 28 rear (radial/2x). They’ve already shipped the first few sets, and they’re available now through their website. Demo sets will be at Interbike’s demo day, too. Retail ranges from $1,385 for ATX26 alloy, carbon starts at $2,050 CCX40 and runs up to $2,195 CCX56 depending on depth. Choose from eight logo decal colors.
