Crank length 175 vs 172.5

Is there, or could there be, any advantage to train with a longer crank arm and race with a short one?

I don’t think so. The body can be sensitive to small changes in fit and movement pattern so I always advocate athletes keep things the same between race and training set up; i.e. you’ll likely perform better if you’re feeling super dialed on your race set up.

Absolutely agree Coach A. After bike racing as a way to keep my legs in shape for ski racing, Ive picked up endurance riding again. Even the smallest changes on my bike can cause knee pain or a myriad of other problems. Fractional change can mean the diff between misery and a comfortable ride. That crank set change would be enormous.
