These Tire Repair Plugs refill a Dynaplug kit with two plug types in one pack, so sealing a tubeless flat doesn't come down to guesswork. Three Soft Nose plugs handle the punctures seen most often, with a brass tip that slides in clean without scraping a rim. Two Megaplugs step up for a cut or gash bigger than sealant can close, using a thicker aluminum tip built for more material. Every plug pushes straight into the hole and bonds on contact, with no tube to swap and no glue to wait on. What Our Gearhead(R) Experts Are Saying:"I check the size of the hole before I grab a plug. A clean pinhole gets a Soft Nose, but once I see a real tear chewing through sealant, I'm reaching for a Megaplug and getting back to the ride."
