The frame seems similar to the Ritchey P-29er but has several differences to set them apart. The frame tubing profiles and geometry were all dialed down to attain the perfect ride feel for the 27.5″ wheels.
A huge benefit for Ritchey is that they are able to develop the mountain bikes as a system with all of the components in their own building, making it stout where it needs to be while still giving the lively ride that steel hardtails are known for.
To end up with an outstanding Ritchey product, the tweener wheels, carbon fork and tires all had to be designed to mate perfectly with the 275 mountain bike.
The new 2013 fork is full carbon with QR dropouts and lands in at 615 grams with the straight style steerer. Retail on the b-tweener carbon fork will be $499 USD, and they are rumored to add a tapered model for next year. The Ritchey 27.5in wheels are made tubeless ready and built out of the alloy Vantage II with the tubeless rim strips installed with valve stems. The rims’ inner width is 20 millimeters. This new wheel set weighs in at 1587 grams with a 15mm thru axle front and standard quick release for the rear. The Ritchey 650B mountain bike tires will be sold in WCS level only for the Shield tread pattern in a 27.5×2.1. Weight is 533 grams.
All of Ritchey’s new 650-b-tweener products are available now.
Their QR axle is included to use the 650 wheels with quick release forks.
The seat stays were able to remain thin for compliance since they didn’t need to be reinforced to handle braking loads. The beautiful sweep in the tube was designed to clear the brake caliper.
Ritchey didn’t use replaceable dropouts since it’s not as big of a deal on a steel bike. With many years developing steel mountain bikes, they can deduct that you are able to bend a steel hanger back into shape many times without any issues.
The total bike weight with their new WCS Paradigm pedals landed at 21 lb 3oz. The steel 650-b hard tail frame will be available in odd numbers starting from as small as 15in up to as big as 21in. The price will retail for the 650 frame at$
