Product Details

Designed for everything from downhill to trail, Ochain N enhances every 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 N features internally adjustable degrees of travel—start with 9º but choose between 6º 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 N is the most robust yet, offering re-engineered impact resistance and enhanced sealing for better contamination resistance and longevity.

About SRAM
SRAM was founded on a single product when Grip Shift shifters were introduced to the road bike market in 1988. SRAM was eager to grow, both by acquisition and product development. Adding core brands Rockshox, Avid, Truvativ and Zipp and pushing component technology has cemented their place as a powerhouse in the industry.
