Ochain

Ochain R, External Adjust, SRAM 3-Bolt, B1

Ochain Ochain R is a performance-focused crank spider that adds controlled rotation between the crank and chainring to reduce the pedal kickback riders feel when suspension compresses and chain growth loads the drivetrain. By isolating those impacts at the spider, it helps the bike stay calmer through square-edge hits and repeated chatter, while keeping power delivery familiar when it’s time to pedal.

Built for easy setup on the bike, the Ochain R External Adjust version lets riders tune how much decoupling they want without tear-down, making it a practical upgrade for enduro and gravity bikes where suspension activity and drivetrain feedback can fight each other.

Tuning and compatibility details

1. 4/6/9/12° external adjust - Quickly balances bump compliance versus direct pedaling feel, based on terrain and riding style
2. Pedal-kickback reduction - Limits chain-growth feedback reaching the feet for smoother control when the suspension is working hard
3. Suspension-friendly drivetrain behavior - Reduces drivetrain-induced resistance during compression to help the rear end move more freely through impacts
4. New Easy system adjuster - Designed for simpler, faster setting changes compared to internal-only adjustments
5. Re-engineered durability and sealing - Improved impact, longevity, and contamination resistance for wet, dusty, and high-load riding
6. SRAM 3-bolt + 104 BCD chainring requirement - Fits 104 BCD chainrings in 32–36T; chainring and bolts not included
