A puncture in your tubeless tire doesn't have to be a death sentence for your ride. This handy carry-along tool repairs small punctures and cuts in tubeless bicycle tires without removing the tire from the rim, getting you back on the trail in no time. The TPT-1 easily plugs the hole by inserting one of the 5 included vulcanized rubber plugs into the puncture. This shrinks the puncture down to a manageable size, allowing the tubeless sealant to do its job and reestablish a seal. The unique sliding plug retainer holds the plug in place and prevents it from being pulled back out as the tool is removed. Everything is stored in a compact package that fits easily in a saddlebag or backpack pocket. - Includes 5 vulcanized rubber plugs (refills available -- part #2370K) - Dimensions: 89 x 27 x 40 mm (3.5" x 1.1" x 1.6") - Weight: 79 grams (2.8 oz.) with plugs NOTE: Intended for tubeless bicycle tires using sealant only. Not compatible with inner tube systems.
