AIRSISTANT by Schrader.
Airstant is an App that keepss your tyre pressure under control via a simple app. It si very simple to apply and install. The device itself is screwed on the actual value. A QR Code is scanned, a bit of information is typed into the app and off you go. You tyre pressure is measured and far more important you get a recommedation to go by.. Do we need this? I have currently only tested the app on a road bike. Tarmac..no. Not vital. Road surface remains the same, hence not need to change the tyre pressure.
I still need to try it out on a gravel bike, this is where it kicks in. Different terrain, bike packing, more weight.. maybe even tubeless…Hmm.. a little help..? I think so.
