I hear ya. funny how much time i’ve spent over the years thinking i’ll just get a nice little kit for each bike, then each year I get on a bike and realize it has only a partial kit or no kit, because I probably went on a big ride in previous year and robbed an item from it. should be so easy, but the tire kit gremlins are sneaky little bastards…
Small is the usual and obvious goal, so for me the dynaplug little setups are what i usually get (which seem overpriced, but I usually end up with those as they’re small and they work), then either a few co2’s and the adaptor, just to get me to someplace for a proper air fill, or if its a bigger bike with carrying capacity i’m now popping in one of the Fantik (costco, amazon) cordless inflators, since i use those for more subtle pressure adjustments as well. But it’s the off-road bikes with tubes that give me the headaches… hate having to carry irons, a tube, and all that, because its so much stuff, its a drag to have to use on the trail, and on those kind of bikes there’s less room and more stuff needed. For ADV bikes i just get or convert to tubeless, but dirt bikes i’m always fiddling with “smaller” vs “easier to use”, based on what mood i’m in that day.
