Stans Original Dart Tubeless Repair Tool. Dual Action Repair for Tubeless (DART) repairs large punctures and slices in tubeless tires faster easier and more reliably than existing tire plugs.

The DART anchors into a puncture while creating a simple and safe chemical reaction with your Stans sealant to quickly form a permanent airtight bond.
