E*Thirteen Helix R Crankarms

E Thirteen has love for aluminum. Knowing lightweight, confidence-inspiring strength, and stunning looks are top priorities for pros and customers alike, they went after all three with a vengeance. The Helix Race is their top-of-the-line aluminum crankset, with XC weight and EWS-worthy Enduro strength. Forged AL6066-T6 crank arms were engineered to maximize stiffness and strength while minimizing excess material. Massive amounts of CNC optimization can be seen on almost every surface, creating an eye-popping, top-tier technical aesthetic and weight savings. A 30 mm diameter, forged AL7050-T7 spindle delivers added stiffness and further reduced overall weight. E Thirteen's P3 spindle interface and updated self-extractor bolt system promises ease of service for years to come.
