" Specials " e*thirteen Helix Race Crank 170x73mm no BB, no ring with Self Extractor Bronze

e*thirteen has love for aluminum. Knowing lightweight, confidence-inspiring strength, and stunning looks are top priorities for our pros and customers alike, we went after all three with a vengeance. The Helix Race is our 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 30mm 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. Helix Race cranks are compatible with Boost and SuperBoost chainlines via versatile flip-flop Helix Race Chainrings, which come in a full spectrum of Helix colors, allowing matching with Helix cassettes and other e*thirteen components. e*thirteen's exclusive, creak-free proven Quick Connect interface keeps the system secure, and Helix rings are fully cross-compatible with both Shimano™ and Sram™ 11 and 12-speed drivetrains, future-proofing your ride. Helix Race Cranks include our newest APS preload adjuster system and custom crank strike boots to keep these beauties looking fresh. Helix Race Cranks....Carbon killers? You be the judge!
