HIGH-END IS NOT RESERVED FOR CARBON ALONE

Gravity riders value aluminum's impact resistance and dependability, but until now, aluminum cranks came with a stiff weight penalty. At e*thirteen we love the look and durability of aluminum, so we put our engineers to work designing a new aluminum crank that leverages the modular spindle design of our carbon cranks and adds sweet machined arms to the equation.

Our Helix Race Aluminum crank is a top-of-the-line aluminum crank that brings Enduro strength at a Down Country weight: just 556g for 165mm.

Extensively weight-optimized, almost every visible crank surface is CNC machined from a burly forged blank. Available in black, bronze, and silver, and compatible with Boost or Super Boost chainlines by using our e*thirteen Helix Race Direct Mount Flip-Flop Chainrings.

  • Engineered to deliver Down-County weight with Enduro strength
  • Forged, CNC Machined AL-6066-T6 arms and 30MM AL 7050-T7 spindle
  • Compatible with Helix Direct Mount Chainrings for Boost/Superboost Chainline
