SRAM XX T-Type 12-Speed Bosch E-MTB Gen4/Gen5 Direct Mount Aluminium Chainring – Black

Designed for the specific demands of electric bikes, the SRAM XX T-Type 12-Speed Bosch E-MTB Gen4/Gen5 Direct Mount Aluminium Chainring is a technical benchmark for assisted drivetrains. Developed in collaboration with SRAM drivetrain engineers, it meets the challenges of high torque and accelerated wear specific to e-MTBs.

This chainring is specifically optimised for Bosch compatibility, covering the BDU37 (CX Gen4) and BDU38 (CX Gen5) motors and ensuring seamless integration with these electric-assist systems.

Its T-Type tooth profile improves chain retention for more efficient pedalling and reduced wear over time, even under heavy loads.

Made from aluminium and compatible with AeroGuard, it complies with the EN 15194:2017 standard, providing reassurance on reliability and safety.
