There’s been a movement in the industry lately with riders switching to cranks with shorter arm lengths. Doing so is supposed to lead to better aerodynamic efficiency, reduced hip flexion, improvement of power balance, or being able to maintain a higher cadence over longer durations.

The cranks are now available in 155mm, 160mm, 165mm, 170mm, and 175mm lengths. The spindle options are 118mm, 122mm WIDE, 130mm Boost, and 136 DUB Wide 55mm Chainline for customizable Q-Factor, and compatibility with various drivetrains.
