Switching between wheel A and wheel B may require a slight adjustment, since not all rear hub spacings are exactly the same. If the 2 hubs are of the same model you should be ok, but different brands can vary a little bit.
When I switch wheels with my mechanincal group, I often have to turn the cable adjusting screw a revolution or so.
Ideally, there would be some very thin shims to put behind the cassette so you can make your wheels all the same.
Does anyone know of such shims ?
