Finish Line releases FiberLink Tubeless Sealant

Published August 10, 2021

LONG ISLAND, N.Y. (BRAIN) — Finish Line released its newest product, FiberLink Tubeless Sealant, a low-viscosity latex formula that seals punctures up to 8mm.

FiberLink Technology consists of Kevlar fibers to work with natural latex to seal punctures. The natural-latex cures rapidly and seals the puncture while Kevlar fibers flow to the puncture, linking and intertwining. During development, this hybrid idea was internally referred to as "a double-sealant with triple benefits."

Other features and benefits

  • Fast-acting natural latex reduces air loss.
  • Optimum longevity between refresh cycles.
  • Low odor and easy to set up.

Purchase options

FiberLink is now available in the U.S. with global availability starting this fall. With a focus on both local bike shops and home mechanics, Finish Line offers FiberLink Tubeless Sealant in:

  • 8oz squeeze bottle — MSRP $12.99.
  • 32oz bottle — MSRP $34.99.
  • 1 gallon jug.
