Can't honestly say I see a whole lot of difference particularly between the 175mm, and 172.5mm
6 feet, don't remember my inseam. 175 on one road bike and the MTB, 172.5 on the other road bike.
And I've noticed a TON of difference between the 175 and the 172.5. My comfortable cadence goes up about 10 rpm, and my power goes up with it. Part of that's probably the completely different bike, but I think part of it is the crank length as well.
I didn't expect to see a difference, but my feelings led me to believe otherwise.
