Satanic Watch Winder
OK, I know this has been hashed over many times in the past, but with little consensus. So, I have a question. For the last 13 (or more) years I've had 175mm crank arms on every bike I've owned. The bike I built in January has 172.5's. I couldn't pass up the deal I got on this crankset. Yesterday while climbing, I heard what I think was BB noise so, this morning, I grabbed my other bike with 175's. Although the ride was virtually flat, my hip flexors were on fire 30 miles out and I cut my ride off early. The 172.5 crank arms never felt different from the175's of the last several years, but today the 175's just plain hurt. What's up?
