I’ve used an Elite turbo trainer: the type that relies on the weight on the rear axle to apply the correct pressure on the roller. With my 20” wheeled Trice it worked fine, although there was minimal clearance between the tyre contact point and the roller housing nothing rubbed. It did tend to eat tyres however, and it doesn’t seem you can get 20” trainer tyres.
Then I thought I’d get a Tacx smart trainer to use on my VTX (because the lightly laden rear wheel wasn’t apply enough pressure on the Elite’s roller) but I cannot get it to work satisfactorily. After diligently adjusting the roller tension as per the app, it’s very hard work and according to Zwift et al I can barely get it going anything like real world speeds, (no more than a simulated 10mph and that’s going ”downhill”!) even it it feels like I’m busting a gut. Oddly there is no issue when I put a DF on the trainer instead.
