Minimum speed when riding rollers

I have a set of rollers and a single-speed road bike. My 80-90 rpm speed is 27-30 kph (17-19 mph). I feel like I would be more stable with higher rpm, but it's harder to sustain.

If I understand this, the source of the bike's stability is the gyroscopic effect of a spinning wheel. So there are few more variables to that, like a wheel's mass, or even distribution of the mass within a wheel body. For the reference, my wheels are 27" and 1.5 kg (3.3 lbs) each, and I'm 70 kg (154 lbs) myself.

Can you share an experience with the speed-stability relation of a road bike on a set of rollers?

• Stability primarily comes from the geometries of the head tube, fork, stem, and handlebar. Aug 30, 2020 at 5:20

• Your wheels are probably 622mm. The "27 inch" measure needs to go away because its too confusing. ETRTO numbering is designed to be impossible to get two measurements meaning the same thing, or one measurement meaning two different things.

• @Criggie Are you sure? In bike tire sizes 27" is 630mm and 28" 622 or (rarely) 635mm.
