SRAM's T-Type chainring for Bosch motors in 36T, in the version for the Bosch CX Gen5 (BDU38) drive unit. SRAM designed it for the high torque and wear of eMTB riding, with the T-Type tooth profile for chain retention and a steel build for long life.

Highlights

  • 36T steel direct-mount chainring for Bosch CX Gen5 (BDU38)
  • 55mm chainline (CL55)
  • T-Type tooth profile for Eagle Transmission
  • Also runs Eagle and 11-speed chains, per SRAM
  • SRAM lists it as AeroGuard compatible

Built for motor torque

Steel teeth stand up to the extra load an eMTB motor puts through the drivetrain, and the T-Type profile gives a smooth, secure pedal feel.

Compatibility and fit

For the Bosch BDU38 (CX Gen5) drive unit; the CX Gen4 (BDU37) uses a different SRAM part. It's a 1x, 12-speed ring for T-Type chains and is backwards compatible with Eagle. Fitting needs Bosch-specific tools, so we recommend a workshop.

This SRAM component is covered by SRAM’s warranty against defects in materials and workmanship; terms are set by SRAM. Wear and service items (chains, cassettes, brake pads, rotors, tape and seals) are normal maintenance parts.

Tune Cycles can supply, fit and set up SRAM components and lodge any warranty assessment on your behalf — book at tunecycles.com.au/book.
