Finish Line Promise The Utopia of Tire Sealants

Finish Line’s new tubeless tire sealant will last the life of the tire, company says

Finish Line’s Tubeless Tire Sealant solves problems presented by other sealants, the company said.

“We wanted to develop a sealant that wouldn’t have any of the negative characteristics of existing latex-based sealants,” said Hank Krause, the president and CEO of Finish Line. “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.”

The company said the sealant will not cure inside the tire once installed, so it doesn’t need to be refreshed every few months to maintain effectiveness. Instead, the company said the sealant will last the entire usable life of the tire. The sealant contains no liquid latex or ammonia and is naturally non-toxic, hypoallergenic and safe for carbon fiber rims. The sealant cleans up easily with water. The company also said the sealant is not affected by the use of CO2 inflators.

The sealant uses DuPont Kevlar fibers called FiberLink. “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,” the company said.

The sealant will be available in 1-gallon bottles for shops and rental fleets, as well as 4 ounce, 8 ounce, and 1 liter consumer sizes. All sizes will be available from Finish Line’s domestic and international dealers in time for the 2018 season.

MSRP is $8.99 for 4 ounces; $14.99 for 8 ounces; $35.99 for 32 ounces and $139.99 for the 1 gallon container.
