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.

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.

Rider Height	Typical Inseam Range (For Reference)	Recommended Crank Length
Under 150cm (< 4'11")	Under 70cm	`140mm`, `145mm` or `150mm`
150-160cm (4'11" - 5'3")	68 - 75cm	`155mm` or `160mm`
161-170cm (5'3" - 5'7")	74 - 80cm	`160mm` or `165mm`
171-180cm (5'7" - 5'11")	79 - 86cm	`165mm` or `170mm`
Over 180cm (> 5'11")	Over 85cm	`172.5mm` or `175mm`
