Sram Ochain R 8-Bolt Direct Mount Active Spider B1 - 104 BCD

Sram Ochain R 8-Bolt Direct Mount Active Spider B1 – 104 BCD

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 on the crankset, those degrees aren’t multiplied by the gear ratio jumps of wide-range cassettes. No surprises, just consistent performance across trail and enduro bikes, where pedaling efficiency is key.

The latest generation of Ochain R is the most robust yet, offering re-engineered impact resistance and enhanced sealing for better contamination resistance and longevity

TUNES WITH EASE
With a simple turn of a dial on Ochain R, it can be tuned for different terrain types, ride styles and bike designs. Designed for the full range of trails and machines, from short travel and highly versatile, to DH-specific and free ride. Because all riders deserve this feeling.

MUTES DISTRACTION
Ochain measurably reduces pedal feedback and chain turbulence to enhance perception and amplify focus. Its ability to “quiet the chaos” Sram didn’t even know was happening is soothing and surprising. It’s as though our feet come alive, able to better connect with the bike, to truly feel what’s going on. Like never before.

BOOSTS CONFIDENCE AND CONTROL
By allowing the chainring to rotate backward, Ochain decouples the rider from all three forces of pedal feedback. A simple, spider-based solution that greatly enhances suspension feel, stability in rough terrain, and traction while braking and cornering. For more confidence, more control, and less fatigue.

SERVICE IT WHEN YOU SERVICE THAT
Full Ochain service intervals align with suspension service (200h of ride time) and can be done by most home mechanics. Thanks to a new sealing system, expect nothing less than super low contamination and super high performance between those intervals.
