What Size For You

165 mm is the shortest crank arm size. With a short crank arm you can do more revolutions. It also gives your feet more clearance from hitting your pegs as you pedal.

170 mm is the middle size. If you aren’t tall and don’t have problems with your feet hitting your peg get this one!

175 mm This size is best for a taller rider.

Personally, I have never ridden 22mm cranks. I probably should because I have snapped over 3 pairs. These cranks have a perfect balance of strength and weight. I like the 2 pc. design and the strong pedal boss!
