E-Thirteen Helix Race e*spec Bosch Gen4 13 mm Offset E-bike MTB Chainring

The E*thirteen chainring has been specifically designed for fitting on e-MTBs equipped with a Bosch Performance CX Gen4 motor. This direct-mount chainring is forged from 7075 aluminium, offering greater stiffness and a longer service life. Furthermore, CNC machining creates a specific tooth profile that offers better chain retention, a useful feature on rough trails. Also worth noting is the external dust guard, which improves integration and protects against external debris.
In terms of drivetrain compatibility, the E*thirteen Helix Race E*spec chainring is compatible with Shimano, SRAM and TRP 11- and 12-speed groupsets. Note that this chainring is compatible with the new SRAM 12-speed T-Type chains.
This model is available in 32 teeth with a 53 mm chainline.
