Helix R Cranks

E*Thirteen Helix R Cranks bring race-ready performance and everyday serviceability together in one impressively light and adaptable package. Designed for riders who demand both precision and durability, these cranks make setup, maintenance, and trail performance feel effortless.

Paired with a lightweight aluminum construction, Quick Connect lockring, and Adaptive Preload Adjuster (APS), the Helix R delivers a secure, dialed-in feel that stays smooth through long rides and rough terrain.
