Air ones are horribe
All are boring
Get trainer road (and a garming speed/cadnce sensor and ANT+ USB stick).
Sufferfest can be ‘fun’.
Drop or Tri bars help as sitting still in one position on the saddle for that long makes even a comfy saddle uncomfortable, so being able to alter the angle of your pelvis helps.
A lot of cheep ones look like Minoura Hypermag resistance units, even down to the remote. If they are then they’re a bargain.
I think it is a bit of a myth about tyres wearing out quicker on a turbo. I have never noticed it.
There’s a quote on the DC Rainmaker site from one of the tyre manufacturers stating that even they think trainer tyres are a rip off. Just use an old worn out road tyre, you’ll retire another road tyre long before you do enough turbo miles to wear the first one out completely.
