The Dynaplug Tubeless Bicycle Tire Repair tools come in two models: the MICRO PRO ($54.99) and the CARBON ULTRALITE ($21.99). Both of the tools repair a bicycle tire by inserting a repair plug in the puncture location. The repair plug bonds with the tire rubber; no glues are needed. More than one repair plug can be used to seal the hole. The Micro Pro tool has the style of a small capsule to keep it very small, and still 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 is has a hollow handle that can store extra items. It comes with one insertion tube and four repair plugs. Both tools use the same repair plugs; extra insertion tubes, micro knife and air stopper are available directly from Dynaplug. Tire repair plugs come in packs of 5. Both of these tools are easy-to-use, neat and fast, have a LIMITED LIFETIME WARRANTY and are MADE IN THE USA.
