More about e*thirteen MTB Cranksets

Your crankset takes more abuse than almost any other component on your bike. We build ours to handle it, whether that's XC racing, all-day trail missions, or sending it at the bike park.

Helix Race Carbon is the most technologically advanced crankset we've ever produced. At 366g (170mm arms), it's light enough for XC racing yet robust enough for aggressive all-mountain riding. Carbon arms paired with a machined aluminum 30mm spindle and 8-lobe splined interface. Complete with a 32T chainring, you're looking at around 415g while meeting ASTM 4 standards.

Helix Race Alloy delivers XC weight with enduro strength. Forged AL6066-T6 arms with massive CNC optimization create an eye-popping technical aesthetic while maximizing stiffness. The Loam Wolf called them "the sexiest alloy crank I've laid eyes on."

Helix Race GR was engineered alongside our World Cup DH and Enduro athletes for downhill, bike park, and freeride. Exceeds ASTM 5 standards with 73mm and 83mm spindle options. A work of art made to take a beating.

Every Helix crankset features a 30mm spindle, self-extracting bolts, APS preload adjuster, and molded crank boots. Cross-compatible chainrings work with SRAM® and Shimano® 11 and 12-speed drivetrains.
