e*thirteen Helix Race GR Direct Mount Chainring

Helix Race GR chainrings are gravity-optimized direct mount chainrings specifically intended to be used with Helix Race GR cranks. They are designed to withstand the punishment of downhill, bikepark, and freeride disciplines. They're crafted of AL 7075-T6, forged, and then CNC'ed for optimized weight, ample stiffness, and great looks. Paired with 83mm spindle Helix Race GR Cranks, -7mm offset GR chainrings produce a 56.5mm chainline suitable for most long-travel bikes. Our Quick Connect Direct Mount spline provides proven security and creak-free mounting. Featuring e*thirteen's M4 narrow-wide tooth profile, GR Rings deliver improved chain retention, reduced noise and system wear, and seamless compatibility with both Shimano(R) and SRAM(R) drivetrains (including T-type(R)). Available in 34T and 36T sizes and Black or Sterling Silver color options. *83mm crank requires the Helix GR Chainring. 73mm crank requires a standard Helix chainring.
