A gravity-focused direct mount chainring built to pair with e*thirteen's Helix Race GR 83mm-spindle cranks, for riders hammering downhill, bike park and freeride lines.

Highlights

  • Forged AL7075-T6 aluminium, CNC-finished for strength and low weight
  • M4 narrow-wide tooth profile for better chain retention and a quieter drivetrain
  • -7mm offset gives a 56.5mm chainline on 83mm-spindle Helix Race GR cranks, suited to most long-travel bikes
  • Quick Connect Direct Mount spline for a secure, creak-free fit
  • Compatible with Shimano and SRAM drivetrains, including SRAM T-Type
  • 34T or 36T, in Black or Silver

Tooth profile and drivetrain compatibility

The M4 narrow-wide tooth profile keeps the chain seated over rough ground, cutting noise and drivetrain wear, and works with Shimano and SRAM 11/12-speed chains, including SRAM's T-Type chains.

Compatibility & fit

This GR chainring is built specifically for e*thirteen Helix Race GR cranks with an 83mm spindle; it is not interchangeable with the standard Helix chainring used on 73mm-spindle Helix Race cranks. Check your crank's spindle length before ordering. The Tune workshop can fit it as part of a drivetrain service or crank swap.
