FiberLink Tubeless Sealant patches punctures before they slow you down
What Our Gearhead® Experts Are Saying:
"I set up my gravel tires with FiberLink Tubeless Sealant before a rocky backcountry loop and rolled over a sharp piece of shale without even noticing until I checked my tires later. The seal held instantly, and the low odor made setup way less of a chore in my garage."
A sharp rock at speed shouldn't end a ride, and FiberLink Tubeless Sealant from Finish Line is built to make sure it doesn't. Picture a rocky descent, tires humming over loose shale, one line hits a puncture, and the ride barely breaks stride. That's the moment this sealant is made for, patching the hole before it ever becomes a problem.
Underneath that quick response is a pro latex formula reinforced with interlinking Kevlar fibers, giving punctures something to grab onto and seal fast instead of leaking air mile after mile. It stays low viscosity so it moves freely inside the tire, and it's built to last between refresh cycles, so you're spending more time riding and less time patching up in the driveway.
