Cassette adjustment question
My primary rear wheel works great on both of my road bikes. It has a 10 speed IRD 11-34 cassette. Bike A has a Deore XT RD paired to DA 7800 shifters. Bike B has a Rival Mid-cage RD.
The problem is when I try and use my backup wheel. It has a ten speed SRAM PG1050 11-32 cassette. It doesn't shift right on either bike. I suspect that the distance from the hub to the cassette is different on the two wheels. Can I use spacers to adjust that distance on the backup wheel (I don't want to touch the primary wheel or the RDs since they work perfect now)? Or is there some other way to adjust the distance? If I use spacers, is there some way to measure something to get the right distance or is it just a matter of trial and error to find the right spacer?
Thanks,
Cliff
