The DynaPlugger™ is a simple, rugged, rad way to repair your tubeless tire. Just find the puncture, align the tool, push into puncture, pull out and the plug stays in place. Now you're ready to get back to shredding! Dynaplugger™ is a molded of Glass-Filled Nylon. Even though it weighs only 35 grams, this tool is extremely strong. The push-on silicone end cap can store an extra insertion tube and seals the interior storage compartment. What's our favorite thing about this kit? We collaborated with our friend NOTCHAS to create its awesome packaging! "This is the first packaging I have ever designed. It’s even cooler because it’s for a product that I LOVE and carry with me on every ride." - Chas Limited Lifetime Warranty - Made in USA - PAT 8,707,829 - ONLY FOR USE WITH TUBELESS BICYCLE TIRES Dynaplug® DynaPlugger™ KitWhat's in the box:1 - Dynaplug® DynaPlugger™ Tool4 - Standard Plugs1 - Standard Insertion Tube1 - Mega Insertion Tube1 - Pipe Cleaner General Specifications Tool Body Construction Glass Filled Nylon Body and Cap / 6061 Aluminum Insert / Silicone End Cap Dimensions 4.875” x .875” Weight 35g Insertion Tube Hardened 303 Stainless Steel Plug Material Viscoelastic Impregnated Rubber Plug Tip Nonabrasive Brass/ 6061 Aluminum Warranty Limited Lifetime
