Ochain E to S Conversion Kit

The Ochain Ochain E to S Conversion Kit is a targeted service solution for riders running an Ochain spider on a compatible SRAM crank setup. It’s designed to convert a compatible Ochain “E” configuration to an Ochain “S” configuration, helping dial in the correct spider standard for the drivetrain and crank interface being used—without replacing the entire Ochain assembly.

• Purpose-built conversion - Updates a compatible SRAM Ochain spider from E to S configuration for correct fit and compatibility
• Service-part approach - Replaces only the necessary components, keeping an existing Ochain setup in service instead of starting over
• Clean, correct installation - Helps maintain proper crank/spider interface alignment when switching Ochain standards
• Category-correct replacement - A focused crank spider service kit for riders maintaining or reconfiguring SRAM-based builds
