Matching group sets on Tacx Flux S and Cheap Bike.

Hi all.
First post. Great forum.
Been riding for a few years but more seriously since buying a Cannondale Synapse in the Spring of 2018.
I bought a Tacx Flux S a few months back and having been using the Synapse on that which I find annoying.
I put a 105 cassette on the Tacx in order to match the 105 on the Synapse.
My question is whether I have to find a bike with a 105 group set to match or will any derailer work with the 105 cassette?
Many thanks and Happy New Year to all.

    Any Shimano groupset or SRAM with the same number of gears.

    If I were you I'd be looking for a winter bike and put your good bike on the turbo.

    Thank you.
    Will consider that option too.
