performance difference between ultega short cage and tiagra mid cage derailleur..
I'm running a 12-25t so i know both will work, but i'm wondering if i'm really going to be able to tell the difference or should i just keep my tiagra on for now or until i break it in a crash???
Also, i'm running a campy ergo 9 speed with the proper jtek.
