The Dynaplug Combo Plug Pack puts two plug profiles in one refill, so a flat tire doesn't come down to guesswork. Three Soft Nose plugs handle the punctures we see most, sealing fast with a brass tip that won't scrape a rim on the way in. Two Megaplugs step in when a cut or gash in a tubeless tire is bigger than sealant can manage, using a thicker aluminum tip built for more material. Either plug pushes straight into the hole and bonds on contact, so there's no tube to swap and no glue to wait on. What Our Gearhead(R) Experts Are Saying:"I size up the hole before I reach into the kit. A pinhole or thin slice gets a Soft Nose plug, but the second I see sealant spraying out of a real tear, I'm grabbing a Megaplug and moving on with my ride."
