Minoura RDA-800 Rim Drive Trainer ” Red 5 Levels.
Rim Drive clamps to the braking surface on rims for consistent and smooth grip, great for knobby tires, upgraded model with a 0.8 kg steel flywheel, 8kg, 100kg capacity.
Great stability with fold down legs for easy storage, double sided axle clamp with crank style tensioner and right side centering adjustment, fits 100-145mm OLD, micro adjust roller pressure.
Quiet magnetic resistance with 5 settings adjustable by a dial knob on the resistance unit, 26″ 700c wheel range.
Will not work on disc specific rims, requires min, 8mm brake surface.
These do look interesting but I think I’d need to have one for a while to try out to be convinced.
