SRAM’s most advanced eMTB chainring, made specifically for Bosch drive units. This 36T version mounts directly to the Bosch BDU38 (CX Gen5).

Highlights

  • Two-piece build: steel teeth, aluminium spider
  • T-Type tooth profile for chain retention and wear life
  • Direct mount to Bosch BDU38
  • Gap cap included
  • AeroGuard compatible, meets EN 15194:2017

Built for motor torque

The aggressive T-Type teeth hold the chain securely for a smoother, more efficient pedal feel, with a focus on long wear life. SRAM notes a larger ring reduces chain loads that drive system wear.

Compatibility and fit

For Bosch BDU38 (CX Gen5) drive units only; Gen 4 needs a different ring. Works with Eagle and T-Type 12-speed chains. Fitting needs the right tools and torque settings from SRAM’s service information, or 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.
