Finish Line introduces longer-lasting tubeless tire sealant

by James Huang

Tubeless tires continue to gain popularity on the road, and the tire and rim technology continues to improve. However, roadies have still been dealing with the same sealant issues that mountain bikers have for two decades now. Even if you never puncture, latex-based sealants will slowly cure inside the tire, losing its effectively over time and eventually hardening if it isn’t refreshed every few months.

Finish Line claims to have finally solved the problem with its new (and creatively named) Tubeless Tire Sealant, which the company says will last the life of the tire without needing to be topped off or replenished with fresh fluid. Developed in partnership with industrial and military supplier Multi Seal, Finish Line also says its new sealant is both latex- and ammonia-free, safe to use with carbon rims, and cleans up with plain water.

Sealant manufacturers use a variety of different approaches to plug holes, and Finish Line touts its use of Kevlar fibers to help seal bigger punctures.

“When a puncture happens, fibers rush into the wound and quickly stop air loss,” states a press release from Finish Line. “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.”

Finish will offer its Tubeless Tire Sealant in 4oz, 8oz, and 1-liter sizes. Prices will vary by region.
