2XR Crank Arms

Cranks arms make the legs go round. Available in 100mm, 135mm, 145mm, 155mm, 160mm, 165mm, 170mm, 175mm crank lengths.

The body can perceive as little as 1mm in difference in crank length, but 10mm actually changes the angles of the knee and hip a useful amount.

Strong and stiff, the pocketing in the insides of the crank arm reduce weight while minimizing stress risers and maximizing fatigue life.
