e*thirteen Helix Race Alloy GR Crankset

Helix Race Alloy GR Cranks - 160x73mm, Black

Our World Cup DH and Enduro teams asked, and e*thirteen delivered. We engineered the new Helix Race GR Cranks for gravity riders who love the CNC aesthetic and exceptional performance of our Helix Race cranks but desire something explicitly designed for the rigors of downhill, big bike park laps, enduro and freeride. The Helix Race GR shares the modular spindle design, low profile shape, and minimal Q-factor of our top-end carbon and alloy cranks and adds gravity-specific 83mm and 73mm spindle options for long-travel geometries. Forged from AL-6066-T6 and CNC optimized, Race GR cranks easily exceed ASTM 5 standards — a work of art made to take a beating.

Engineered impact resistance and ultimate strength for Downhill, Bike Park, and Freeride

Forged, CNC Machined AL-6066-T6 arms and 30mm AL 7050-T7 spindle

Pair 83mm spindle cranks with Helix GR Chainrings for a 56.5mm chain line, and 73mm cranks with Helix Race Chainrings for a 55mm Boost chain line
