I recently purchased a container of Black Ox Sealant for my gravel bike tubeless setup. I’m riding on Maxxis Ramblers 40mm tires. I was able to install the sealant with the use of a Topeak Joe Blow Booster Tire Pump. Installation of the sealant was easy. The Black Ox Sealant has carbon particles in the sealant to help improve the bead seal and fill a puncture. The sealant comes with a wide diameter plastic tube to increase the flow rate of the sealant as you add the product inside the tire. Just make sure you shake the container very well to mix up the carbon particles in the sealant. The sealant cleans up easily with soap and water. On 9/19/2020, I competed In the Dirt Diggler Gravel Race in Brevard North Carolina. The gravel roads in the DuPont Forest are very rugged; I competed the event without experiencing any tire issues. No flats and no tire burps causing the sealant to leak out from hard rock impacts. I competed in the Master Men 27 mile 2300 feet of elevation Division finishing 12 out of 19. I’m impressed with the Black Ox Sealant and will be purchasing more products to support a great local based N.C. Company.
