My reference to sprinting was that they push a lot harder, and at even higher rpm's, and they don't blow their knees up.

Sometimes it just feels good to stand and mash, but also, I like it because it uses different muscles.

To each their own I guess, and the OP will probably never notice the difference between an 11 and 12 tooth smallest cog. I just can't stand the comments about your knees blowing up every time you put in a hard effort below 60 rpm's.
