The cycling industry has long had a one-size-fits-all policy when it comes to crank arm lengths.

Tall people with relatively short cranks will have a wide saddle height ’sweet spot‘, where a change of a few mm in either direction makes little difference. If the cranks are too
Since a short crank results in a higher gain ratio, With a low profile crank, the pedal ends of the arms stay in the same place, but the axle is shortened, and the arms run at an angle, outward from the bottom bracket toward the pedal end. Low profile cranks save a bit of weight, and are also potentially stiffer. The design is a real
