Thanks. I'll take a look when I get home. I'm going to trade them in for 160mms. Since my knees have started to bother me I've heard that shorter cranks help. Sheldon Brown's site says that unless you are riding a single speed, there is no mechanical advantage or disadvantage to crank length. This should take some pressure off.
On that note, can anyone recommend a bottom-of-the-barrel crank set that comes in 160mm? I don't want to spend more than like $150.
I'm obviously not a racer. Or a mechanic.
