While at the Bentonville Bike Fest 2022 we came across the Finish Line Fiberlink Tubeless Sealant. I had only run Finish Line chain lubricant in the past, but not tried the tubeless sealant. Well, the Ibis Ripmo AF needed a sealant change, or at least some sealant since at this point I knew the sealant in the Maxxis Minions had dried up.

Finish Line Fiberlink – The Ride

Finish Line Fiberlink Tubeless Sealant works well for a range of applications. Mountain Bike, Gravel Bike, and Road Bike Tires. Running this sealant on the Ripmo AF has gone well so far. There are plenty of 90 degree edge rocks there in Austin, TX to put the sealant to the test. Unlike some of the tubeless sealants I’ve used in the past, FiberLink has yet to dry out or get thick and rubbery. Another observation was the inner surface of my 29 inch Maxxis Minion DHF 2.6 tires doesn’t have the expected residue so the usual cleaning process was not necessary. Just a simple brush out works well.

Finish Line claims the sealant can last up to 4 months. I’ve reached two and a half months and the sealant is still running strong. This claim varies depending upon the environment you’re in, given riding conditions, temperature and how many sniper rocks you’re hitting on each ride. With how hot it has been in Austin, TX, we’ll see how this goes. Once I reach that 4 month mark, I’ll see what the FiberLink looks like on the inside of the Minions and report back here.

What is FiberLink™ Technology?

Finish Line: “Kevlar® fibers work synergistically with fast-acting natural latex to seal punctures as they occur. Free-flowing latex cures rapidly to create an adhesive seal which is reinforced with interlinking Kevlar fibers.“

Installation

Quick installation of the sealant was a breeze right out of the gate. There is a quick and easy sealant dosage guide on the back of the bottle. Want more details? See the QR code on the back of the bottle for additional help. For my 29 inch Maxxis Minion DHF 2.6, I used 4oz for the front and 4oz for the rear. With this bottle I wanted to avoid using the measuring cup or syringe. The FiberLink fluid is this and smooth without alot or any grit or grainy substance.
