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 a new chainstay-mounted rear disc brake mount save a few more grams. And like every frame Ritchey makes, geometry and tubing is carefully fine-tuned by Tom, to bring the legendary balanced, nimble Ritchey feel to 27.5-inch wheels. - Weight: 2,028g for frame (L/17”) - Ritchey forged-and-machined 1.5” tapered head tube - Clearance for up to 2.25-inch tires - Fork: Designed for use with 100mm travel forks - Headset: Integrated 1.5” tapered - Upper bearing: 41.8mm OD / IS42/28.6 (S.H.I.S.) - Lower bearing: 52mm OD / IS52/40 (S.H.I.S.) - Bottom Bracket: 68mm English threaded - Rear spacing: 10x135 - Front derailleur: 28.6 low clamp – top or dual pull - Weight: 2178g / 4.8 lbs (M/17”, frame only)
