Finding the right crankset means matching strength, stiffness, weight, and fitment to your bike and riding style. Our cranksets span mountain bike, E-MTB, and gravel with options from ultralight carbon to gravity-rated alloy.

For mountain bike builds, Helix Race Carbon delivers the highest strength-to-weight ratio we've ever produced at just 366g, meeting ASTM 4 standards while handling everything from XC racing to aggressive trail riding. Helix Race Alloy brings premium forged construction with stunning CNC-sculpted aesthetics. Helix Race GR exceeds ASTM 5 standards for downhill, bike park, and freeride with 73mm and 83mm spindle options.

Don't just take our word for it. The Loam Wolf called the Helix Race Alloy "the sexiest alloy crank I've laid eyes on." Bike Perfect also recommended it, calling it a "beautiful CNC sculpted alloy crankset" that is a "a stiff yet relatively lightweight option"  Worldwide Cyclery called the XCX "the most durable XC crankset I have seen and ridden to date."

E-MTB riders get purpose-built espec cranks in shorter lengths for pedal clearance on modern geometry. Wide motor compatibility covers Bosch®, Brose®, TQ®, Fazua®, Avinox®, and Specialized® systems. Carbon espec cranks weigh as low as 320g while meeting ASTM 5 standards for shuttle-day strength.

Gravel riders get our lightest cranks ever with the XCX Race Carbon Gravel at sub-360g. Decades of World Cup racing experience in a patented design built for riders who count grams and chase KOMs.
