Puncture size determines which plug works. The Pro Tubeless Kit from Lezyne includes both 1.5mm and 3.5mm plugs—5 of each size stored inside the aluminum housing—so you can match the repair to the hole diameter. Small punctures from thorns or glass shards seal with the narrow 1.5mm plugs, while larger cuts or tears require the wider 3.5mm diameter to fill the damage and maintain seal integrity. That dual-size approach removes the guesswork when you're fixing a flat on the trail or roadside.

The integrated tool system consolidates repair equipment into a compact aluminum case. The stainless steel reamer/inserter tool prepares the puncture and installs the plug in one operation. A plug retention tool holds plugs during insertion to prevent them from pulling back out of the tire. The included valve core remover lets you remove cores when adding sealant or checking tire condition. A Presta-compatible CO2 inflator threads onto the valve after the plug seats, providing quick reinflation without carrying a separate pump. The micro knife trims excess plug material flush with the tire surface after installation.

The aluminum housing doubles as a handle during plug insertion—you grip the case while working the reamer tool through the tire casing. That design eliminates separate handles or tools that take up additional space in your pack. At 50 grams, the complete kit fits into saddle bags, jersey pockets, or hydration pack compartments without adding noticeable weight. The case dimensions allow it to nest alongside multi-tools or CO2 cartridges in most storage systems.... Read More
