Stan's Original DART Tool w/ 2 Darts in Black/Silver

Dual Action Repair for Tubeless (DART) Tool

The Dual Action Repair for Tubeless (DART) Tool was unveiled in 2019, ushering in the first repair plug designed specifically for tubeless bicycle tires, rather than a scaled-down version of what was available in the automotive and motorcycle world. Subsequent refinements made way for the tool's rerelease as the Original DART Tool in 2025, introducing a stainless steel insertion rod accompanied by an improved DART developed through the first tool's lifespan.

By using a flexible, laser-cut material, the DART conforms to nonuniform puncture shapes caused by the jagged and sharp edges of debris and obstacles found on trails, roads, and paths. Treated with a reactive solution, the DART bonds with liquid sealant on the inside of a tubeless tire to form both a chemical and mechanical seal to permanently bond a puncture too large for tubeless sealant to repair on its own.

Features:

• Dual action: mechanical fill created by the unique insert, and a chemical reaction that activates sealant to quickly form an instant permanent airtight bond.
• Barbed plastic tip anchors into the tire, without rim damage or cut hands.
• Flexible fabric bonds with sealant, and will not pull out while riding.
• Wears off clean, no trimming needed, cannot be felt while riding, even on road tires.
• Lightweight, compact tool has an ergonomic shape for precise use.
• Clear cap unthreads quickly for rapid deployment.
• Tool includes two DART applications, and a built-in valve core remover.
• Updated stainless steel insertion rod.
• Repairs punctures and slices too large for sealant alone to seal.
• Base of tool features molded Presta core tool for sealant top-offs.
• Clear caps keep DARTs clean and unthread for quick use.
