e*thirteen Helix Race Carbon Crankset - 165mm, 73mm, 30mm Spindle, 8-bolt Chainring Interface

Helix Race Carbon Cranks are a milestone in carbon crank design. Featuring highly optimized carbon crank arms and lightweight 30mm aluminum spindle, these cranks dramatically reduce weight while maintaining incredible strength. Weighing in at just 335g (170mm), they exceed ASTM 4 test standards, making them equally at home on everything from Aggressive Trail and All Mountain rigs to feather-weight XC Race builds. The Helix Race Carbon utilizes an 8-bolt chainring interface (chainring sold separately), with a twist. By incorporating a unique four-bolt locking mechanism in their Helix Race 8-Bolt Chainring interface, weight is further reduced while improving longevity (standard 8-bolt chainrings also compatible). Available in popular crank lengths of 165mm, 170mm, and 175mm, Helix Race Carbon cranks come equipped with molded crank boots, an APS adjuster, captive pedal washers, and a convenient self-extractor system, ensuring simple installation and maintenance. If you're looking for the highest strength-to-weight ratio in MTB cranks, you just found it!
