UPDATE: CLASSIFIEDS section refreshed, redesigned, searchable: Go take a look
I saw one recently but cant remember where I saw it but it looked like you just remove the rear wheel and bolt onto the trainer?
Any direct drive one. There's loads out there. E.g...
Tacx Neo or Flux
Cyclops Hammer or Silencer
LeMond Revolution
Elite Drivio
Wahoo Kickr
There are quite a few now. Just google "direct drive turbo trainer".
Are some better than otjers or all much of a muchness?
The DC Rainmaker website has a lot of in-depth reviews/comparisons (as well as [i]long[/i] comments sections from users which give a helpful "real world" view).
I bought the Tacx Neo in the winter based on his recommendation of it being the "best" & I've been very happy with it.
Things have moved on
