Longer or shorter chain?
I just recently changed out my rear cassette and want to do everything the right way. I am wondering if i would need a longer or shorter chain? I went from an 7 speed 14-28 cassette to an 7 speed 13-34 cassette. I would guess a longer chain, but could be wrong. I have some new noises with the new cassette when i switch to the lowest gear while climbing hills. Also, i'm usually in the lower gears and never go any higher than the 17 ring on the cassette.
