Designed for everything from aggressive enduro to all-day trail, Ochain E enhances every E-MTB ride with next-level confidence and control. Its spider design allows the chainring to rotate backward, decoupling the rider from pedal feedback forces. 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. Ochain E features internally adjustable degrees of travel—start with 9º add 12° to match terrain, riding style, and bike setup. And because Ochain is mounted at the motor, those degrees aren’t multiplied by the gear ratio jumps of wide-range cassettes. No surprises, just consistent performance. The latest generation of Ochain S is the most robust yet, offering re-engineered impact resistance and enhanced sealing for better contamination resistance.
