Whether you're sending it on a steep descent or grinding through an all-day epic, the Ochain R redefines what it means to feel in control. Its redesigned next-generation spider lets the chainring rotate freely backward, effectively isolating you from pedal kickback and chain slap. The ride gets quieter, the trail gets clearer, and your focus stays exactly where it belongs, on what's ahead. The real confidence boost comes from what you don't feel. With chain turbulence dramatically reduced, riders report greater stability under braking and through corners, even when the terrain fights back. Rough and rowdy? That's where Ochain R thrives. Dial in your ideal ride feel with the external travel adjuster, choose from Lock, 3°, 6°, 9°, or 12° of travel to suit your terrain, style, and bike setup. And since Ochain mounts directly to the crankset, those settings stay true regardless of where you are on the cassette. No gear-ratio surprises, no inconsistency, just predictable, confidence-inspiring performance every time you clip in. Built tougher than ever, the latest Ochain R B1 features a re-engineered impact-resistant construction and improved sealing to keep dirt, mud, and moisture out, so it lasts longer and performs better, ride after ride.
