Can you elaborate on this? I’m on the smart Nero rollers though I don’t use them in erg mode (I prefer using the gears).

Tyre slipping only, when rollers gives high resistance during sprints or climbs.

Got it, thanks. I found higher tire pressure addressed that problem for me.

Minimum setup is ‘some rollers’! I’ve been using rollers for many years (have only every trained indoors on them) and have just used my road bike, with whatever wheels and tyres are on there. You might need to adjust your tyre pressure slightly to find a good level - I run mine slightly harder (~80psi) for rollers than outside (tubeless setup) as it then feels like there is a bit less tyre ‘squish’.

Been using the Nero since 2019 with my road bike and have not noticed any tire wear. Do use them interactively but usually no more than a 5% grade. Recently I got a gravel bike with 40 tires. Much more tire noise but still easy to ride.

So with another roller thread revived, I decided to give indoor training another chance, but this time with rollers. My Kickr Core got taken to college by my daughter.
Recently I purchased the Elite QM rollers as recommended. It didn’t take as long to get a hang of things as I had anticipated. My question has to do with tire pressure. Outside, I ride clinchers with 92psi (front) and 94-95psi (rear). Should I keep the same pressure inside on the rollers? Some have recommended as high as 115psi. I run Vittoria Corsa 28mm with Tubolito tubes.
Thanks
If anything I run lower pressure for more resistance with my elite QM rollers but now I’m questioning if that’s right. I get lots of tire squeal noises if I move side to side on the rollers at all.
So I’d say start with the same as outside and see how that feels. But I’d also say you’re running really high pressure for 28s.
I’d compare your current pressures to the max listed on the tire sidewall. If you are close to that already, I wouldn’t sweat the difference.
As mentioned, you can play with pressure a bit to alter the resistance, but I would hope the 3 level adjustment setting plus you gearing would work in most cases without that manipulation.
This is on the lazier side, but I’ll pump them up to 120 (25mm) simply so that it’s longer between having to pump them up. They’re around 60 or so by the time I notice and re-inflate them. It makes a minor difference in what gear I’m using when I’m actually riding but that’s the extent of it.
The less I have to do before hopping on the rollers the better.

I usually run my tires at max pressure on rollers since it makes them work better with Nero on the interactive changes of resistence and also, I do not have to be worried about traction on wet road on the roller.

Is it my imagination or is higher tire pressure also leading to less (directional) stability? Bike handling seems to be much more ‘nervous’ at high tire pressures.
Yup, that makes perfect sense. The tire will “sink” into the rollers less with higher pressure. That means less “tire wrap” around the roller, with more ability to steer and lean vs lower pressures.
Thanks. Fairly new to rollers and first couple of rides were surprisingly easy. Then I increased tire pressure significantly after reading this thread and was struggling big time to keep the bike on the rollers
