Product Details

From full-on downhill to all-day trail, Ochain S brings next-level confidence and control to E-MTB. 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 at the motor, those degrees aren’t multiplied by the gear ratio jumps of wide-range cassettes. No surprises, just consistent, natural performance. The latest generation of Ochain S is the most robust yet, offering re-engineered impact resistance and enhanced sealing for better contamination resistance.

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.
