40mm Valve Core Extender

Setting up tubeless tires can be difficult. Add a single-wall, flat profile fat rim to the equation, and the setup can be downright frustrating. Problem Solver's oversized Super P-Nut’s help with this. First, the bottom of the nut is concave, so the valve can be pulled further through the rim, creating a better seal. The larger outer diameter of the nut provides better grip and leverage so that you can get the valve tighter than with conventional nuts. It’s like a normal P-Nut. Only more super.

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. - Includes two DARTs, refills sold separately - Repairs punctures and slices too large for sealant alone to seal - Woven, laser-cut material easily conforms to nonuniform puncture shapes - Base of tool features molded Presta core tool for sealant top-offs - Clear caps keep DARTs clean and unthread for quick use
