The rear wheel on my Surly Cross Check is right at the edge of the rear dropout but the chain is tensioned correctly. If I move the wheel back into the dropout so it is comfortably in the middle, I presume that the chain will no longer be tensioned correctly or will it? Does the rear derailleur compensate for wheel shift fore and aft?
If not will I need to get a longer chain? I asked the bike shop but they didn't seem keen on moving the wheel back into the dropout. They just said the rear dropout screws were correctly configured.
