Thanks OP, managed to get one yesterday with British Cycling discount too (y)
Fwiw the current rrp is 550 drspite the misleading was price by Halfords https://road.cc/content/tech-news/248653-tacx-improves-flux-smart-trainer-and-reduces-price
Topped up the heat. Great price, but clearly clearing stock in fear of the silent Kickr Core coming in to ready availability in the next few months.
I've checked mine and it isn't the S, it has the original style legs where the S are lower, and has the Edco not Shimano Freehub. It is 2018 though, there is a barcode on the box marked "W 2018" and "T290020180500".
Do you mean not the Flux S? Apparently the internals of the "non S" vary: https://www.dcrainmaker.com/2018/09/tacx-flux-s-smart-trainer-first-look.html "there’s actually a substantial difference internally between an original ‘2016 Flux 1’, and a new 2018 Flux 1. Even after that clarification it can remain confusing, as a 2018 Flux 1 manufactured in January will vary in comparison to one made in June 2018. I say June, because that’s when most of the changes were incorporated into the product line"
