I just recently bought a second bike, a new hybrid/mountain bike made by cannondale. It will serve me good use for offroading and winter biking because of the thicker tires and shocks. I was wondering if I could take off its gear shifters and switch them to my Giant road bike that is 3 years old. Both bikes have shimano gear shifters that are 3 and 8 speed, but the new bike has disc brakes and the gear shifters say "Shimano V-Brake" on them, I don't know if it makes a difference. The main point is I like these shifters more and they look a lot nicer so I would like to put them on the better bike, could I switch them over or will this not work?
