Tacx NEO 3m 12 speed

[znerken]

In the tac-x manual it states that

this was a little too ambiguous for me. If using a 12 speed ultegra 8150 cassette, do I need a spacer or not? Is there any spacers installed on the pre installed 11 speed? If you want as much clearance as possible from the flywheel, can I just install both the 1 and 0.5 mm spacer to get as much clearance as possible?

I’m running a CS-R8101 (12 speed Ultegra cassette) with no spacers.

I simply removed the 11-speed cassette that came with the neo and installed my 12-speed cassette.
