My inherited road bike has 2x8 system, but the rear cassette is done and too rusty. Still driveable, but I'd prefer to change it. I have in my garage a nice set of older Mavic wheels what are faaaar better than the current, the only problem is that there is a 7-speed cassete (mint condition). I plan to just swap the whole wheel. My question, would adding a 7-speed cassette to 2x8 system would cause issues with shifting performance? I assume that the chain might jump off once I shift to the low or top gear?
