Helix Race Carbon Cranks

Helix Race Carbon Cranks are the most technologically advanced cranks we’ve ever produced—robust enough for all-mountain excursions, yet light enough for XC race rigs at just 335g (170mm arms). They feature carbon crank arms paired with a weight-saving, machined aluminum 30mm spindle and an 8-lobe splined interface. Complete cranksets with chainring weigh in at under 400g, all while meeting ASTM 4 test standards. Designed for versatility, Helix Race Carbon Cranks are ideal for everything from featherweight XC race builds to aggressive trail and all-mountain setups—and they do it all with refined, understated styling that complements any high-performance build. 

These cranks utilize an 8-bolt chainring interface with a twist: our Helix Race 8-Bolt Chainring incorporates a unique four-bolt locking mechanism that further reduces weight. Available in 160mm, 165mm, 170mm, and 175mm lengths, Helix Race Carbon Cranks come equipped with molded crank boots, an APS adjuster, captive pedal washers, and a convenient self-extracting system for easy installation and maintenance.

*While the unique design of e*thirteen’s 8-Bolt chainrings requires only 4 bolts, if you are using 8-Bolt standard rings from other brands, all 8 bolts must be used. 

160mm length coming soon.
