Behold! Our fastest repair tool for tubeless bicycle tires...the Dynaplug® Racer. Why do you need this? It plugs holes, massive holes that sealant won't stand a chance against. Beneath one cap you'll find our new Megaplug (3 times the thickness of our standard plug). It's a real time saver when you have a large puncture. Have a smaller puncture? Pull off the other cap and our standard plug is ready to go.
