This is an easy DIY swap to get the right crank length. It took me 15 minutes to swap my 172.5 to 165, and I upgraded to Red in the process (would have bought Force, but they weren't in stock). These cranks are, obviously, light and look good. But if you're worried about being able to DIY, then a simple set of wrenches are all you need.
Great carbon crank
Great cranks. I went from 175s and 165s and have zero regrets.
