Hey Guys, I have a road bike that is a 7 speed freewheel in the back, and I had a question, let say I want to upgrade the rear derailler to something in the higher end Shimano, instead of the 2200 on the bike right now, I want to put Tiagra and above.
I was wondering if I would run in any problems? I assume that high end rear deraillers like tiagra and above only take 8+ speed cassettes. This is where the noob in me starts, I dont know the specifics of this. Are there Rear Deraillers of Tiagra that work on 7 speeds or are they universal?? Sorry I am a big time noob at this stuff, but I am reading a bike mechanic book as we speak.
