Running separate wheelsets

Hi Everyone,
If you're running separate wheelsets and the cassettes are of different gearing - 11/25 and 11/32 - what are the chances you'll need to adjust your derailleur everytime you swap wheelsets?
Using an 8-speed triple.
Thanks
Mike

If your chain length and rear derailleur is set up to handle the 32, you shouldn't have any problems.

Seems to me your chain will be too long when you have the 11/25 wheelset on.

You did say "TRIPLE", so there shouldn't be any problem if you are set up for the 11-32 and it currently works correctly. Chain length wouldn't be any different than if you were taking off in 3rd gear (or so).

Any adjustment required would be because the cassettes weren't centered the same from the DS locknut.
Thin shims/spacers could adjust that dimension if needed.

Another thing to think about is rim width, if you're using different model rims. If they're not the same width, you'd likely need to adjust the brakes every time you switch wheels-

Nope. The little/little gear combination doesn't change so, if the chain wasn't too long with one it won't be too long with the other.
