Helix Race Alloy Crank Arms

E*thirteen’s Helix Race Crank Arms combine lightweight design, impressive strength, and striking aesthetics. Engineered with XC-level weight and Enduro-worthy durability, these top-tier cranks feature forged AL6066-T6 arms crafted to maximize stiffness and strength while minimizing excess material. Extensive CNC optimization enhances the technical appearance and weight savings, while a 30mm forged AL7050-T7 spindle adds rigidity and reduces overall weight. The Helix Race Crankset offers versatile compatibility with Boost and SuperBoost chainlines through its flip-flop Helix Race Chainrings, available in a full range of vibrant Helix colors to match with e*thirteen cassettes and components. The Quick Connect interface ensures a creak-free, secure fit, and Helix rings are fully compatible with Shimano and Sram 11 and 12-speed drivetrains, future-proofing your setup. The cranks also feature the latest APS preload adjuster system and custom crank boots to keep them looking new. E*thirteen
