Shimano 12 speed cassettes?

Hello everyone.

I have two new sets of wheels, one with an m8100 cassette, the other with no cassette.

When I swap wheels, do I?

A) just swap cassettes as well.

B) buy another m8100

C) buy an m7100 or m6100.

If I went for C, is there an issue of sharing the chain between say the 6100 and 8100?

OCD says B.

I go with A myself on my gravel bike. You’ll have a bias to one set in the end anyway. I do have two sets of rotors mind.

If swapping often; buy another cassette the same.

If not swapping often; move the cassette over too to avoid any uneven wear between the chain and cassette.

I’d definitely put another m8100 on and also shim the rotors if required so everything lines up nicely. Makes swapping wheels painless

Oh and buy the most expensive Shimano chain you can afford. It’ll save you money in the long run…
