The Ochain E Active E-Bike Spider for Brose/SRAM 55mm setups is designed to improve the ride feel and suspension performance of e-MTBs. By introducing controlled rotation between the crank and chainring, it helps isolate pedal feedback caused by chain growth, creating a smoother and more natural pedal stroke—especially on technical terrain.
With 9 degrees of rotational movement, the Ochain system minimizes the harsh feedback that can reach the rider’s feet, enhancing comfort and control. The updated construction increases durability to handle the torque and demands of modern e-bike drivetrains. Compatible with 104 BCD chainrings, it fits 32–36t sizes for versatile gearing options.
