Crankarms

160mm vs 170mm

160mm and 170mm refer to the length of the crankarms on a bike. The length of crankarms affect the rider's pedaling efficiency and comfort. Ultimately, the choice between 160mm and 170mm depends on individual preferences and riding style.

A longer crankarm (170mm) can provide more leverage, making it easier to pedal but also harder to spin quickly. 

A shorter crankarm (160mm) requires less leverage, making it harder to pedal but easier to spin quickly.
