I have the same question, my bike has a 11 32 cassette. I need like for like so the limit screws are set correctly. Will the 11 32 fit ok on the tacx neo 2t. Zwift helpdesk have said they only sell the 11 25 and can't promise will fit.
As kdx200 said a year ago, as long as this is a standard Shimano 9, 10, or 11 ring cassette it should fit the free hub that comes with the Tacx NEO 2T.
The difference in number of teeth between the smallest ring and the largest ring should only affect whether the rear derailleur you have will work with the cassette. The technical specifications for your rear derailleur should state what the maximum difference is.
yes 1 spacer to hub , otherwise rear caliper in some edge positions ( bike moves) touched trainer . not a big deal but with spaces it is safe , no more contact .
