Tacx Flux S - which adapter?

[willpgmiller]

Hi there,

I have recently purchased a Tacx Flux S trainer. My bike is a Pinnacle Arkose 2019, with the rear through-axle.

I need an adapter, I purchased the 142x12mm adapter however I'm not sure this is the correct one, there still seems to be some play.

There are a whole load of adapters online, I'm not even remotely sure which would fit. Can anyone help?

The original axle with the bike reads '(172) / M12xP1.5-20L'

Any help much appreciated.

Thanks,
Will
