Ochain R, 104 BCD, Sram 8-Bolt , B1

Tune out pedal kickback and smooth out rough trails.

The Ochain R is an active spider designed to reduce the effects of chain growth and pedal kickback on full-suspension mountain bikes. By allowing controlled rotation at the spider, Ochain helps separate suspension movement from the crankset, giving the bike a smoother, more chainless feel through rough terrain, braking bumps, rocks, roots, and big compressions.

The R version features external travel adjustment, allowing riders to fine tune the amount of spider rotation between 4, 6, 9, and 12 degrees. This lets you balance suspension sensitivity, pedal feedback, and pedaling efficiency based on the trail, riding style, or bike setup. The updated B1 version also includes the new Easy System adjuster with improved impact, longevity, and contamination resistance.
