Designed for DH to trail, Ochain N enhances every ride with next-level confidence and control. The result is a quieter bike with reduced chain turbulence and noise, allowing riders to stay fully focused on the trail ahead. Choose 6°, 9°, 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.
Includes: Ochain N Spider, 6º travel chip, 12º travel chip, and spider to crank mounting bolts

Virtual 3mm offset when paired with SRAM XX 104bcd T-Type Chainring for CL55 compatibility. Additional 3mm spacers and hardware required for CL56.5mm DH compatibility.
