Ritchey P-650b Frameset

Outstanding price on this modern classic. Limited quantities available.

This is the second version of a 650b mountain bike from Ritchey - Tom started to design his first in 1977. Even back then, Tom had a feeling that there was an advantage to the "middle" wheel size, but it took the rest of the cycling world three decades to figure it out: a 650b (or 27.5") wheel provides the bump-eating smoothness of a 29er, with the light, responsive feel of 26" wheels. Finally, the era of the 650b wheel is here.

The P-650b is a close relative to the P-29er. Up front there's the proprietary forged-and-machined, gram-shaving integrated head tube featured on all new Ritchey frames. Forged socket dropouts and new chainstay-mounted rear disc brake mount save a few more grams.

Tom Ritchey applied over 40 years of racing, designing and building steel mountain bikes into the new P-650b. Like any Ritchey, this bike is born to go fast without sacrificing comfort or durability. Heat-treated, triple-butted Ritchey Logic II tubing in Ritchey's unique butting profiles results in a frame that balances rough trail compliance with sprint-winning stiffness.

Build information: requires BSC (English) threaded bottom bracket cups, 27.2 seat post, 1 1/8" integrated headset (Logic Zero WCS drop in 1-1/8" (41.8 Campy), 100mm travel fork and 28.6 clamp-on, top pull front derailleur. This frameset requires a 1 1/8" straight steerer 27.5"/650b fork. Please call 800-627-6664 for fork options.
