Ochain

S Active E-Bike Spider - Brose/SRAM

The Ochain S Active E-Bike Spider - Brose/SRAM brings suspension performance and drivetrain refinement together for e-MTB riders who want a smoother, more controlled ride. By introducing adjustable rotational movement between the crank and chainring, the Ochain system helps isolate pedal feedback caused by chain growth, giving the sensation of riding chainless while maintaining full power delivery.

Adjustments can be made externally, allowing riders to fine-tune the amount of rotation for their terrain or riding style without disassembly. The result is improved suspension sensitivity, reduced pedal kickback, and a more natural pedal feel on technical trails. Designed for 104 BCD chainrings, it fits 32–36t sizes and integrates cleanly with Brose and SRAM e-bike systems.
