e*thirteen Helix Race Carbon Crankset - 165mm 73mm 30mm Spindle with DUB Interface. Helix Race Carbon Cranks are a milestone in carbon crank design. Featuring highly optimized carbon crank arms and lightweight alloy DUB interface 30mm 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 separate) 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 youre looking for the highest strength-to-weight ratio in MTB cranks you just found it!
