I already have some small CO 2 bottles I carry on my regular bike. I do know the 3” x 20” tires on my new upcoming purchase will require more air than I’m used to putting in. So -if I top off or just use a manual air pump to begin with, what’s lighter to carry/ use ?. what do you guys carry ? I would either have to carry in the rear basket or on a stand alone mount. I’ve seen many of the small rechargeable compressors, I think I’d rather go old scool w/ a type of manual unless I’m convinced otherwise. Can’t say I’ve had any flats while riding on the street. My new adventures will include some dirt trails and amongst the trees/ shrubs/ etc my odds increase to get a flat.
