Hi,
I currently ride 172.5mm cranks, but have the opportunity for a good deal on a new 175mm crank set.
I have no reason to change, other than the opportunity for some new kit.
I wasn't specifically measured to 172.5mm cranks, it's just that they came with the bike.
What would the pros/cons be of changing to a longer crank length?
Thanks

I wear 34 pants and always road with a 175 crank. when i bought my new bike last fall the shop insisted that I get 172.5 cranks. I did and I didn't notice anything until the crank broke and I put on my old 175's. I feel much better on 175 cranks. I am sure it is a persomnel preference thing in that a friend who is my height likes 172.5 cranks better than 175.

If you are 4' 2", I would advise against it. If you are 5" 7" or taller, go for it.
