A steel direct mount chainring for e*thirteen's 1x cranksets, built for riders who want a tougher, quieter ring than alloy without changing their setup.

Highlights

  • 30T, steel construction
  • Flip-flop ring: 52mm (Boost) or 55mm (Super Boost) chainline
  • M4 narrow-wide tooth profile for chain retention
  • QuickConnect direct mount, black

Compatibility & fit

Fits e*thirteen Helix, TRS, LG1 and XCX direct mount cranks, 10/11/12-speed, and runs on both Shimano and SRAM 11/12-speed drivetrains. Flip the ring to switch between a 52mm Boost and 55mm Super Boost chainline on the same crank. The Tune workshop can fit it as part of a 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.
