Working alongside our World Cup DH and Enduro athletes, e*thirteen engineered the new Helix Race GR Cranks. These Forged AL-6066-T6, CNC-sculpted aluminum cranks are designed for the rigors of downhill, big bike park laps, enduro, and freeride. The Helix Race GR shares the spindle design and low-profile shape with our top-end carbon and alloy cranks, with 83mm and 73mm spindle options. Helix Race GR cranks easily exceed ASTM 5 standard — a work of art made to take a beating.
