e*thirteen Helix Race Carbon Crankset

Helix Race Carbon Cranks - 160x73mm, Graphite

Helix Race Carbon Cranks are a milestone in carbon crank design. Featuring highly optimized carbon crank arms and lightweight alloy 9-lobe interface, 30mm spindle, these cranks dramatically reduce weight while maintaining incredible strength. Weighing in at just 335g (170mm), sub-400g including chainring, 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, with a twist. By incorporating a unique four-bolt locking mechanism in our 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!
