haven't seen anything on TTF yet about the flux, Steve Irwin seems to have found some way of making the Neo at least as good/better than the Lemond, but seems to require constant connection with a tablet, once not in the right mode its seemingly no better than a kickr or a turbo muin...
I was reading into it on TTforum and I am not so sure.
TT forum love a good talk over turbo trainers.
