Getting rear wheels to match

I've bought a spare rear wheel to use as a home trainer with my turbo, however although I've added an Ultegra cassette (as per my normal set up), when I use the spare wheel the gears are out of alignment and I seem to spend most of the time adjusting them rather than riding, then trying to adjust them back again once I'm done on the turbo. Also, the rim doesn't sit in the same position either as it runs on one brake block.

Is there a way to adjust the position of the hub on the wheel... apologies, it's not easy the describe... I don't mean to adjust the dish of the wheel, but so that when the wheel is on the bike the position of the cassette is correctly positioned in relation to the derailleur, so that it matches my main wheel?

The wheel dish issue I can sort separately.
Still trying to convince the missus of the n+1 rule...!

    The short answer is no...
    then of course, anything is possible, moving the spacers around on the turbo cassette, for instance, but in principle no solution is hassle free.
    As for the dish, I suppose it's no big deal on the turbo, just keep the rear caliper open

    Might be a daft question but....

    Assuming it was a cup and cone type bearing set-up on the wheel, would it be possible to adjust both sets of cones and locknuts to move the whole hub assembly to the left or right?

    If the gear misalignment was marginal, this could do the trick maybe?

    I appreciate it probably means that one of the wheels is not centralised properly in the first place, but was just wondering? :?: :?:

    move the hub on the cones for the turbo wheel, then open the rear caliper.

    If it isn't cup and cone and adjustment is only slightly out then a cassette spacer can do the trick if you're lucky.

    Thanks for the replies. To be honest I don't know if it's a cup and cone so I'll take a look at that first and then investigate how to adjust.

    Why not have a cheap bike for the turbo and one for the road. Or then again just get out on the road. Sorry I just don't like turbo's rollers for this hassle.

    I understand what your saying, although I have to use what I've got and can't always get out, especially when we're shrouded in fog and zero temps as we have been for the last few days... the turbo just helps me keep the legs going :)
