The Dynaplug Racer Pro improves upon the legendary Racer's original design with Twin Tube technology. This allows you to store x4 pre-loaded plugs ready to go in a single tool. Snap-on caps protect plugs from dirt and damage. When your ready to make a repair, just pop off a cap to deploy either a standard size plug (with wheel-friendly soft brass tip) or the aluminum Megaplug for mega-big punctures. If you need more plugs just unthread the Twin Tube and flip it around for more plugging action! Machined in Chico, CA from US-made billet aluminum and stainless steel, the Racer Pro weighs 26g, only 2g more than the prior generation, yet delivers twice the puncture-defeating power!
