ethirteen Helix Race Alloy GR Cranks

ethirteen Helix Race Alloy GR Cranks Info

e*thirteen Helix Race Alloy GR Cranks are engineered for riders who punish equipment on downhill tracks, bike park laps, and full-gas enduro stages. Developed alongside World Cup DH and Enduro athletes, these cranks are built to deliver uncompromising strength, precise power transfer, and long-term reliability in the most demanding riding environments.

The Helix Race GR Cranks are forged from AL-6066-T6 aluminum and CNC-sculpted for an ideal balance of stiffness and impact resistance. Paired with a robust 30mm AL-7050-T7 spindle, the system shares the same proven spindle architecture and low-profile shape as e*thirteen’s top-tier carbon and alloy cranks. The result is a gravity-focused crankset that exceeds ASTM 5 standards, making it fully suited for downhill, bike park, enduro, and freeride abuse.

Available with both 73mm and 83mm spindle options, the Helix Race GR adapts easily to modern enduro and DH frames. Thoughtful details—including molded crank boots, protective polymer decals, an APS preload adjuster, and an integrated self-extractor system—ensure durability, easy installation, and simplified service. With gravity-specific arm lengths on offer, these cranks are purpose-built for riders who demand clearance, strength, and confidence on the roughest terrain.
