Behold! Our fastest repair tool for tubeless bicycle tires...the Dynaplug(R) Racer. Why do you need this? It plugs holes, massive holes that sealant won't stand a chance against.

Pull off the other cap and our standard plug is ready to go. This small package is machined from solid billet 6061 aluminum and weighs only 24 grams!
