I hear it all the time "this sealant can't handle punctures" and "that sealant dries out and balls up after two months" or "my sealant doesn't seal punctures or stay liquid". On and on they go, disappointed and frustrated. Searching for answers, searching for a better product, searching for a way to ride tubeless with confidence. Slime Premium Tubeless Sealant is here to save your cycling summer. Does it dry out? I live in Flagstaff, AZ (7,000ft elev. and very dry) and my sealant has been going strong for seven months - SEVEN. What about punctures? Up to a quarter inch gets plugged. You heard me, a QUARTER inch. What about initial set up? Use Slime's new tubeless tape, tubeless valves and Premium Sealant and you'll be set up in no time. I did both of my bikes last weekend in about 25 minutes with no leaks, drips or issues. Isn't Slime for 'cheap' bikes? Well, Slime Tube Sealant is for pretty much anything with a tube and tire. Our new Tubeless Sealant has been formulated specifically for mountain and road bike tubeless with incredible results. This new sealant is a game changer, try it and you'll be amazed.
