Slime Sealant

With the abundance of tubeless tire use in our discipline, sealants abound.

We stopped by Slime, one of the original tire sealants available developed over the past 30 years and has products for motor vehicles as well as bicycles. Tubeless formulations differ, and Slime has been refining its tubeless sealant arriving with a new formula earlier this year that contains very little ammonia. It has particles of various size and composition and better coating than competitors as was demonstrated with clear balls filled with popular brands of sealant that could be swished around.

Slime claims its tubeless sealant will evaporate slower than other brands, perhaps lasting 6 to 12 months before recharging. They wouldn’t let us puncture the balls to compare the sealing capabilities, but we could observe the coating qualities.

We are not convinced that coating capability is the key to success of a tire sealant, but will certainly put the new Slime formula to the test with our decade of tubeless experience!

Slime has a tire plug tool under the brand Genuine Innovations.  It uses the proven gummy plugs and a forked tool, but recently put these into an aluminum integrated kit. The aluminum cylinder holds a film of 6 plugs, a valve core and the insertion tool attached to the cap. There is a valve core tool as part of the cylinder. It weighs 30 grams and goes for $20 USD.
