Stans Dart Tubeless Tyre Repair Tool V2

Stan’s unveiled the Dual Action Repair for Tubeless (DART) Tool 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.

Complete with two DARTs, the tool weighs only 15-grams and fits comfortably in any small pack pocket. For added convenience, the base of the molded plastic tool body features a Presta valve core remover to aid in-the-field sealant topoffs with either a 60ml or 120ml bottle of Stan’s Original Tubeless Sealant.
