No experience with Stans, i’m afraid. But i started using Joes three years ago, and i’m happy to report that i’ve never had to perform a trailside puncture repair. Even through the late summer/early autumn hedge-cutting season.
A pint easily lasts me a year for one bike, adding an ounce per tire about once a month during riding season
Either i’m doing something wrong, or you’re a little eager! I filled my tubes up three years ago, and that’s how they’ve stayed ever since! I changed the tires on one of my bikes last year, so i let them down for that, but the sealant remained untouched.
Just be aware not to let any get into the valve – seems obvious, but i learned the hard way…
Joes, for me!
