e*thirteen Helix Race Carbon Crank - 30mm | 68/73mm | 8-Bolt - black

The crank is robust enough for All-Mountain tours and yet light enough for Cross Country races. The crank arms are made of carbon and connected to a weight-saving, milled 30 mm aluminum axle. This crank is compatible with SRAM 8-Bolt Direct Mount, but there is a special feature: e*thirteen's own Helix Race 8-Bolt chainrings have a unique four-hole locking mechanism that further reduces weight (8 bolts must be used when using chainrings from other manufacturers).
