Punctures too large for sealant to bridge leave you with two choices: install a tube and deal with the mess, or plug the hole and keep riding tubeless. The Tubeless Plug Refill from Lezyne restocks your repair kit with tacky vulcanized rubber strips that bond with tire sealant and tire casing to seal punctures from the outside. Ten plugs give you multiple repairs without carrying spare tubes.

The strips measure 65.8mm long and work with the Lezyne Tubeless Kit or Classic Tubeless Kit insertion tools. Thread a strip through the forked tool shaft, fold it in half, and push it into the puncture. The tacky rubber surface grips the tire material as you withdraw the tool, leaving the plug seated in the hole. Tire sealant bonds with the vulcanized rubber to create an airtight seal that holds under riding pressure.

Each strip handles small to medium punctures that overwhelm sealant capacity. For larger holes, double up two strips on the tool and insert them together. The plugs work across mountain, gravel, and road tubeless setups, though lower-pressure mountain bike tires with knobby tread give the most reliable results. Higher-pressure road tires may require internal patching after the initial trailside repair gets you home.... Read More
