Less Feedback Between You and the Suspension

The Ochain S sits between the Bosch motor and chainring to reduce the pedal feedback caused by chain growth as the rear suspension moves. Its controlled backward rotation takes some of that drivetrain tension away from the rider, helping the suspension stay more active through rough terrain while also calming chain movement and noise.

External Travel Adjust makes it easy to change the amount of rotation without opening the unit. Choose Lock, 3°, 6°, 9° or 12° depending on the bike, terrain and how much drivetrain feedback you want to remove. This version is made specifically for Bosch BDU38 / Performance Line CX Gen 5 motors and uses a 104 BCD chainring.
