How to Choose Your Ideal Crank Length?

Selecting the right crank arm length is crucial for comfort, efficiency, and injury prevention. While a professional bike fitting is always the best approach, you can use your height as an excellent starting point.



Precision CNC Machining with AL-7075-T6 Alloy

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.

Check CRODER's Short Cranks

Our industry-leading range of shorter cranks (140mm-155mm) is specifically designed to benefit cyclists who require higher cadence, such as triathletes, or female cyclists and riders with shorter inseams looking for a perfect, ergonomic fit.
