Hi, I've been struggling trying to find an 8-Speed Campag Mirage shifter for my bike and have managed to locate a Campag Chorus set. I'm aware this is a slightly higher level of Campag products but if I were to buy this set I have found, would it still just as easily fit onto my bike, or are there any reasons as to why I shouldn't do this. Quick responses would be great as I am worried this part will disappear. Thanks!
