@MrAndrewD @bicycling I carry RideNows as emergency spares, but my tires are set up tubeless. I’ve had to press one into service once. It was fine.

They’re delicate in some ways. I carry my spares inside a latex glove (which I’ll want anyhow), and you can’t let them get pinched when mounting them.

Note that if you use an electrical inflator, you need to use a tube with a metal valve (RideNow does offer these) or a hose between the air and valve, because the heat is bad for plastic valves.
