im using a kinetic rock and roll control wheel on trainer, on which I use my retro 1980s 6 speed bike.
It sometimes has problems with wheel slip and really needs a training tyre.
This isn’t a problem as its a permanent fixture on my turbo.
There used to be calibration problems, but now I use Garmin V3s power pedals ( shared with my road bike ). It is BLE only and needs a dongle for my old iMac
I was looking at a direct upgraded trainer, but because of the 6 speed I wouldn’t be able to use my retro bike, id have to swap my road bike on and off.
My current turbo limits me to 10% grade (and a power i’m not sure id ever reach)
It would be nice to get to 20% grade, but in Zwift a real limit ( can adjust difficulty, but I usually ride at 1) of 10% isn’t too much of a problem.
So i’ll stick where I am.
