Ochain

Ochain N, Internal Adjust, SRAM 3-Bolt, B1

Ochain Ochain N is a performance-focused crank spider for SRAM 3-bolt setups, designed to help full-suspension bikes ride smoother under load by reducing the negative effects of chain growth on suspension behavior. With internally swappable travel chips, it lets riders tune feel and traction across different terrain and suspension kinematics without changing cranks.

Tuning and compatibility details that matter

1. Internally adjustable travel angle - Ships with a 9° factory setting, with included 6° and 12° travel chips to tune how the drivetrain interacts with suspension across pedaling and impacts
2. Chain-growth mitigation - Helps reduce the negative effects chain growth can have on suspension performance for better control when the bike is deep in its travel
3. Re-engineered durability and sealing - Updated for improved impact resistance, longevity, and contamination resistance in wet or dusty riding
4. SRAM 3-bolt interface - Built specifically for SRAM 3-bolt crank compatibility for a clean, direct fit
5. 104 BCD chainring requirement - Requires a 104 BCD chainring and is sized for 32–36T chainrings
6. Upgradeable platform - Ochain N can be upgraded to Ochain R using the Ochain External Travel Adjust Upgrade Kit

Note: Chainring and chainring bolts are not included.
