Compatibility & fit

Fits e*thirteen's e*spec direct mount interface on DJI Avinox e-MTB cranksets; the 8mm offset and 55mm chainline are specific to the Avinox version of this ring, so check your motor before ordering. Compatible with Shimano and SRAM 11/12-speed drivetrains. The Tune workshop can fit it as part of an eMTB drivetrain service.

e*thirteen's standard warranty covers this product for 10 years against manufacturing and material defects; normal wear, crash damage and misuse aren't covered, though e*thirteen's Infinite Ride programme offers a discounted replacement after a crash. For warranty support, return the product to Tune Cycles and we'll manage the claim with e*thirteen's Australian distributor. This is in addition to your rights under the Australian Consumer Law, so keep your proof of purchase.
