Finish Line will launch a new tubeless tyre sealant this month.

“We wanted to develop a sealant that wouldn’t have any of the negative characteristics of existing latex-based sealants,” commented president and CEO of Finish Line Hank Krause. “By partnering with MULTI SEAL, a longtime leader in industrial and military tire sealants, we have created a sealant that significantly advances the technology for tubeless bicycle tire sealants.”

Finish Line Tubeless Tire Sealant will not cure inside the tire once installed. Therefore, it doesn’t need to be refreshed every few months to maintain effectiveness. This sealant will last the entire usable life of the tire, according to the brand. 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.

FiberLink technology makes this possible. Utilizing DuPont Kevlar fibers, FiberLink seals are 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 seal.

Finish Line offers its sealant in 1-gallon bottles for shops and rental fleets, as well as 4oz, 8oz, and 1L consumer sizes. All sizes will be available from Finish Line’s expansive network of international dealers in time for the 2018 season.
