Hello everyone... I have a quick question:

I ride an oler Paramount OS2. I just bought some new(to me) STI levers off os ebay. Anyway, I have a hodgepodge of older parts on my rig. I am just getting back into it... used to race juniors back in the early 90's. Am I going to run into compatibility problems with these new shifters? That is aside from the obvious number of cogs... Thanks!

Tex
