Tubeless maintenance is pretty simple. Every 6 months you have to add more sealant. Set a calendar reminder when you do the initial set up, or just wing it. Take the valve core out of the tire. Ideally do this while the bike is not on the ground, or flipped over, so you don’t lose the tire bead seal. Drain the air, pump in 2-4 more ounces of sealant (that ya shook first), put the valve core back in and re-inflate. Done. Ideally, you would use the same sealant as before, but we’ve heard tell of folks mixing sealants with success. I’d say: mix non-foaming latex sealants for best results. IE Stan’s and Orange Seal, but not Orange Seal and Caffelatex. Really though, Orange Seal is easy to get. Just order it from us! If you are maintaining a bunch of bikes with tubeless tires, get one 8 oz bottle of orange seal, which has a handy applicator hose, and one 32 oz bottle for refilling the 8 oz bottle. You’ll save money that way, in the long run, and create less waste.
