Stans Notubes White Stan's No Tubes Dart Tool & Refill, Sports Direct. Stan's No Tubes Dart Tool & Refill Stan's developed the Dual Action Repair for Tubeless (DART) to repair large punctures and slices in tubeless tyres faster, easier, and more reliably than existing tyre plugs. Unlike traditional tyre 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 tyre repair fast, easy, and reliable for every rider. Traditional plug tools were originally developed for car tyres, and their long, sharp tips can cause damage to rim tape, or cut hands. Even worse, their plugs can actually expand many punctures because they rely on only a tight fit to hold them in place. In contrast, the DART’s sonically welded plastic tip and heavy-duty woven material anchor firmly in place and stay put during even the most aggressive riding, while being safer for rims, rim tape, and your hands. The strong and flexible laser-cut material of the DART contours to different punctures and maximizes surface area sealing power. Because the DART anchors to your tyre and creates a bond with your sealant, it also won’t pull out while riding the way a conventional plug can. One of the best features of the DART’s design is that it doesn’t require trimming once inserted, and excess material won’t get in the way of your ride. DARTs can’t be felt while riding, even on road tyres, and they wear smoothly naturally. At only 15g complete, the DART Tool is designed to be extremely light, durable and compact to fit into pockets and packs, while offering an ergonomic design that’s easy to hold and allows precise DART placement. The DART Tool’s handle includes a built-in valve core remover, making it easy to add sealant. The tool is made of ultra-strong but light-moulded plastic. Because even the small details are important, the rod that presses DARTs into punctures is made of ultralight, corrosion-resistant and incredibly strong carbon. The DART Tool is covered by a limited lifetime warranty. Ease of use and rapid deployment were the main priorities in the development of the DART Tool. Its carbon insertion rod is calibrated to let you insert DARTs to the perfect depth every time, just by pressing until the head of the tool contacts your tyre. No more guessing games, or damage to rim or rim tape during a fast repair. The head of the DART Tool is double-sided and reversible, allowing it to hold two sealed DARTs on each side. This makes it possible to install two DARTs quickly when sealing the largest slices and punctures and even multiple punctures. Clear thread-on caps protect the stored DARTS, keeping them clean and ready to use, while being quick to unthread for fast deployment. The DART Tool packs all this repair capability into a compact shape that easily fits in any pocket or pack. The DART makes tubeless tyre repair fast, easy, and reliable for every rider.
