Helix Race GR Direct Mount Chainring - For use with Helix Race GR Crank

e*thirteen Helix Race GR chainrings are direct mount chainrings for gravity riding, including downhill, bikepark, and freeride. Made from AL-7075-T6 alloy, they are CNC machined for low weight and stiffness. With Helix Race GR cranks, the -7mm offset GR chainrings create a 56.5mm chainline for long-travel bikes. The M4 narrow-wide tooth profile provides chain retention, lower noise, and less wear. They work with Shimano and SRAM drivetrains, including T-type. Use with Helix Race GR 83mm spindle cranks for 56.5mm chainline. Not for 73mm spindle cranks.
