SRAM Ochain R Spider External Adjust - Direct Mount interface

Ochain R brings next-level confidence and control. The next-generation spider design allows the chainring to rotate backward, decoupling the rider from the forces of pedal feedback. The result is a quieter bike with reduced chain turbulence and noise, allowing riders to stay fully focused on the trail ahead. It allows riders to be more confident by unlocking greater stability while braking and cornering, boosting control on rough terrain.

The external travel adjust lets riders fine-tune the degrees of travel—choose between Lock 3°, 6°, 9°, or 12° to match terrain, riding style, and bike setup. And because Ochain is mounted on the crankset, those degrees aren’t multiplied by the gear ratio jumps of wide-range cassettes. No surprises, just consistent performance across trail and enduro bikes, where pedaling efficiency is key.

The latest generation of Ochain R is the most robust yet, offering re-engineered impact resistance and enhanced sealing for better contamination resistance and longevity
