We developed the Dual Action Repair for Tubeless (DART) to repair large punctures and slices in tubeless tires faster, easier, and more reliably than existing tire plugs. Unlike traditional tire plugs that attempt to press rubber strips into a puncture, dual action DARTs create both a mechanical and a chemical seal. The DART anchors into a puncture while creating a simple and safe chemical reaction with your Stan's sealant to quickly form a permanent airtight bond. The DART's patent pending ability to react with latex sealant makes tubeless tire repair fast, easy, and reliable for every rider.
