A new standard in tubeless sealant. Finish Line Tubeless Tire Sealant, featuring Fiberlink technology, will not cure inside the tires and doesn’t need to be refreshed every few months to maintain effectiveness. This sealant will last the entire usable life of the tire. Since there is no liquid latex or ammonia in Finish Line sealant, it is naturally non-toxic, hypoallergenic and safe for carbon fiber rims. Additionally, Finish Line Tubeless Tire Sealant cleans up easily with water – no more scrubbing or scraping cured latex from tires and rims. Fiberlink technology makes this possible. Utilizing DuPont Kevlar fibers, Fiberlink seals are extremely robust once they plug a hole. When a puncture happens, fibers rush into the wound and quickly stop air loss. As the tire flexes while it is ridden, the Fiberlink mesh tightens and reinforces itself, creating a confidence-inspiring seal that will last ride-after-ride. - Non-latex ammonia-free formulation - Kevlar reinforced Fiberlink mesh seal - Seals up to 1/4" punctures - Can be used in extreme temperatures, down to -10 degrees Fahrenheit

- Independent, lock-and-seal valve stem for tubeless rim set up - Removable core to allow use of valve extensions if needed (44mm OL) - Sold as pair
