The SPIRIT modular crankset allows for the easy selection and customization of crank arm, axle, spider, and chainring components. It’s designed for cyclists who require short crank arm lengths, which are often difficult to find—particularly for women, climbing cyclists, and triathletes.

Made from AL-7075-T6 aluminum alloy with full CNC machining, the SPIRIT crankset provides the perfect balance of strength and performance, enabling faster and more fluid pedaling.

Every SPIRIT crank arm is precision-crafted from a solid block of premium AL-7075-T6, an aerospace-grade aluminum alloy renowned for its exceptional strength and fatigue resistance.

We utilize a meticulous, time-intensive Full CNC (Computer Numerical Control) machining process. Unlike forged alternatives, this method allows for more complex shapes and tighter tolerances, resulting in a crank arm that is both lightweight and incredibly strong. While some carbon fiber products may present long-term durability concerns, our AL-7075-T6 construction offers a proven balance of stiffness, performance, and rock-solid reliability, ensuring that every watt of your power is transferred directly to the road.
