    I would get a Tiagra cassette for a turbo trainer. No point in paying extra for Ultegra when the main difference is weight.

    They don't make a 12-25, but they do make an 11-25 and a 12-28. So decide if you're better off with more top end or bottom end (which will likely depend on your turbo and it's max gradient) and pick accordingly.

    It should just be a straight swap, but you might need some more links on your chain for the 12-28, and you might need to adjust the B screw on the rear mech. If you're changing cassette you'll likely be changing chain too so cut size to suit.

    Word of warning - component shortage makes it hard to come by anything at the moment. I find eBay seems to be the best chance of getting less common stuff at the moment if you can't find it in Wiggle, Merlin et al

    See your other thread where you posted the exact same question for further options.
