Dynaplug is the fastest, easiest and all-round best way to repair a bicycle 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 ride! The original Micro Pro in polished aluminum and the anodized Pill tools have the style of a small capsule to keep the tool very small, and yet all of the accessories are stored neatly inside and weighs only 1.5 ounces. With this tool, there are five repair plugs along with two insertion tubes, an air stopper and a micro knife. The Carbon Ultralite and Megaplugger have a hollow handle that can store extra items and come with extra plugs as shown in the photos. All Dynaplug Tools have a limited life time warranty and are MADE IN THE USA.
