The Ochain N spider is designed to improve control and ride quality across everything from aggressive downhill tracks to technical trail riding.

Its unique spider mechanism allows the chainring to rotate backward, effectively decoupling the rider from pedal feedback forces. This reduces drivetrain noise and chain turbulence, resulting in a quieter bike and a more composed ride over rough terrain.

By minimising pedal kickback, Ochain N improves stability while braking and cornering, helping riders maintain confidence on demanding trails. The internally adjustable travel system allows riders to fine-tune the degree of rotation to match terrain, riding style and bike setup.

Mounted directly to the crankset, the system delivers consistent behaviour regardless of cassette gear changes. The latest generation also features improved impact resistance and enhanced sealing to increase durability and protection from contamination.
