Got my new wheels which I am very happy with and put a new cassette on them with the exact same range as the other 'old' back wheel. Made a bit of a racket and couldn't get the gears to index cleanly. Put the old cassette on the new wheel and bingo.
Trouble is I wanted to have my old back wheel for using my turbo trainer. But if I put the new cassette on with the old chain it won't seem to work smoothly.
So how do I or how have others got around this?
New chain and cassettes on all?
