Did some sealant mixing experiments with Black OX, Orange seal and Bontrager's TLR. No clotting/congealing. Been rolling just fine in my full sus MTB. :)

I love the Black Ox products from the sealant to the anodized valve stems. I am a gravel rider and I only use Black Ox sealant for durability, confidence. I can ride hard in all terrain conditions knowing I have a lesser chance of tire failure.

The participants that used the Black Ox sealant during the race were very satisfied. They said they had no issues and it was very easy to put into their wheels/tires!

To me, this is exactly how sealant should work. I wanted a product that I put in my tire every few months, and I don't have to think about it beyond making sure my tire pressure is good before a ride. This sealant takes worry out of your head and lets you concentrate on the ride.

I’ve used every sealant out there at one time or another. Black OX2 is the best sealant I’ve used for gravel and road tires. No flats yet after several hundred miles on gravel and asphalt.
