The routine Ochain service part. Fresh elastomers restore the damping resistance that controls how the chainring rotates under pedal kickback, and SRAM sets this replacement every 100 hours.

Highlights

  • Elastomer kit for Ochain Gen B spiders
  • Replacement elastomers and end stroke token
  • New M4 Torx cover screws
  • 100-hour service interval

Doing the service

The spider is removed and the cover lifted off (on R and S the knob goes to 12° first). The four elastomers and end stroke token are replaced and greased, and the cover screws go back in at 4.5 N·m.

Compatibility and fit

Fits Ochain R, N, S and E (Gen B). The 200-hour full service uses the separate full service kit. Fitting needs the right tools and the SRAM service manual, or book it in with a workshop.
