STAN'S NOTUBES DART TOOLREPAIRS LARGE PUNCTURES AND SLICESGoing tubeless on your bike is a wonderful thing. It is lighter than running tubes, allows riders to drop their tire pressure, and provides a smoother ride with fewer flats. Usually, tubeless sealant will fill up most punctures, but sometimes you'll hit something too big to seal up. The Stan's NoTubes Dart Tool repairs large punctures and slices and reacts with Stan's sealant to form an instant, airtight seal. The barbed plastic tip anchors into the tire and doesn't pull out when riding. It wears off clean with no trimming needed. The tool includes two pre-loaded Darts and the clear caps keep the Darts clean.FeaturesRepairs large punctures and slices by reacting with Stan's sealant to form an instant, airtight sealFlexible material and laser-cut shapeLightweight, compact tool fits into your hand with easeIncludes two pre-loaded Darts for sealing multiple puncturesClear caps keep the Darts clean and unthread quickly | Stan's NoTubes Dart Tool 2 Darts included, for MTB and Road Tires
