ok let me see if I can explain this.
For 1 bike I have 2 wheel sets. Should I expect to be able to swap the rear wheels with no adjustment to the derailuer?
Both wheels have a 9 speed cogset. One cog set is a shimano 12-25 the other a SRAM 12-26.
When I put the shimano cog wheelset on the bike for trainer use, I got some cog skipping in the largest 2 cogs.
what is causing this? and How can I fix it? Or is this normal when switching wheels.
