Ritchey P-650b Frameset
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 nd 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-29er. 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.
The 29er-specific geometry was defined by countless hours of saddle time under Tom Ritchey and other racers. The result is nimble handling that captures the benefits of the big wheels, stable but not sluggish, equally at home on all-day epics or tight, technical singletrack race courses.
The P-29 has a slider type dropout system making the P-29er geared or single-speed compatible. Each dropout is held in place with two stout bolts. Beefy adjustable dropout screws keep the dropouts precisely in place with no slipping.
