ethirteen Helix Race Alloy Cranks Info

Helix Race Alloy Cranks represent e*thirteen’s no-compromise approach to high-performance aluminum cranksets. Designed to balance XC-ready weight with enduro-level strength, the Helix Race cranks are engineered for riders who demand stiffness, durability, and refined aesthetics in a single package.

The forged AL6066-T6 crank arms are heavily CNC-machined to remove unnecessary material while preserving structural integrity in high-load zones. The result is a crankset that feels solid and responsive under power, yet impressively light for its category. A 30mm forged AL7050-T7 spindle adds stiffness at the heart of the system while further reducing overall weight.

At the interface, e*thirteen’s proven Quick Connect system delivers a secure, creak-free fit, paired with the P3 spindle interface and an updated self-extracting bolt for long-term serviceability. Chainline flexibility is handled via Helix Race flip-flop direct mount chainrings, making the cranks compatible with both Boost and SuperBoost setups. Helix rings are cross-compatible with Shimano™ and SRAM™ 11- and 12-speed drivetrains, keeping the system adaptable as drivetrains evolve.

Finishing touches include the APS preload adjuster for precise bearing setup and custom crank strike boots that protect the arms from trail damage, helping the Helix Race cranks look as good as they perform.
