Helix Race Carbon Crankset - 73mm with DUB Interface

e*thirteen Helix Race Carbon Cranks set a new benchmark in carbon crank design, delivering an unmatched balance of strength and low weight. With optimized carbon crank arms and a lightweight alloy 30mm DUB spindle, these cranks weigh just 335g (170mm) while exceeding ASTM 4 strength standards. The result is a crankset that's equally suited for aggressive trail and all-mountain builds as it is for featherweight XC race setups.

The Helix Race Carbon features a refined 8-bolt chainring interface with a unique four-bolt locking mechanism. This design reduces weight, enhances durability, and remains compatible with standard 8-bolt chainrings. Offered in 165mm, 170mm, and 175mm lengths, the crankset comes equipped with molded crank boots, an APS adjuster, captive pedal washers, and a self-extractor system for straightforward installation and maintenance.
