This is a direct mount chainring for electric mountain bikes built around an Avinox drive unit. It fixes straight to the splined output of the motor rather than to a crank spider, and its T-Type tooth profile matches SRAM Eagle Transmission drivetrains. The deep tooth shape holds the chain under the torque an electric drive unit puts through it.
Construction is two piece. Steel teeth carry the wear that comes with motor assistance, while an aluminum spider keeps rotating mass in check. Larger tooth counts lower the chain loads that drive wear across the rest of the drivetrain. Fitment is specific to the Avinox motor interface, so this ring will not adapt to a crank based chainring mount.
