As seen strapped to the frames of some of the world's fastest rigs, the Racer is the speediest, lightest Dynaplug tool and just what you want to have on hand when the clock is ticking and the podium beckons. Dynaplug is the fastest, easiest and all-round best way to repair a tubeless tire mid-ride. When needed, just remove whatever caused the puncture, firmly push the novel insertion tube straight (without twisting) into the hole and extract the tool depositing the repair plug in the tire, done! The sealant-friendly repair plug is a unique viscoelastic impregnated rubber that bonds instantly and permanently with your tire, and the nonabrasive brass tip will not scratch your rim or puncture your rim tape. No need to remove the tire, no messy glues or solvents, just plug and go, go, GO! All Dynaplug Tools have a limited life time warranty and are MADE IN THE USA.
