Video: Black Ox Tests its New 'Bulletproof' Tire Sealant Using a Rifle

Sep 14, 2020 at 8:55
by Ed Spratt  


To test out its claims of a 'bulletproof' tire sealant, Black Ox decided the best way was to use a .22 cal rifle. Their new sealant is made from a mix of different lengths of carbon fibers mix with the latex-based sealant, this is said to fill holes of up to 9mm in diameter, which is why Black Ox thought a rifle was the best tool for the job.

The product is made in North Carolina using technology that Black Ox has taken from its parent company which works in the aerospace industry. Currently, you can buy a 4oz bottle for $5.99, a 16oz for $17.99 and a 32oz for $28.99. But it says you will need around 10oz for a 3.8" 29" tire. You can find out more about the sealant here.

 This is America, where you need to make sure your tires are bulletproof so your kids can safely ride their bike to school.

 If this is for the American market, how much of the stuff would you need if these trailfairies have a bumpstock installed? Sounds like it might be a good solution for Mike Levy. Either to help ignite the gas or just to inflate the tire with lead.

 Murica! Biking equipment promo for hillbilly rednecks. Also Scott Pruitt edition with carbon fiber, great!

 How they didn't use an OG Santa Cruz Bullet in this video is beyond me. Maybe even shoot the frame and have sealant leak out and then plug the hole? Anyway, questionable marketing approach aside, I'm sold on this stuff as its been far better than Stans or the stuff from Orange in terms of easy seating and holding air.

Plus, now I'm ready for hunting season around here!

 Why was there a cut in the video while the wheel was slowing down and trying to seal, then after the cut the wheel was now spinning faster and the hole was magically sealed....? If you're gonna fake a video at least get the simple bits right

 Funny how the immediate impulse is (rightfully) to distrust this video, but everyone takes that Santa Cruz video of carbon being stronger than aluminum as gospel...
  • 40 2
 @rezrov: Santa Cruz never claimed that Carbon was stronger than aluminum.
Their claim was that their carbon frames were stronger than their aluminum counterpart.
Anything taken out of context can be manipulated to appear exaggerated or false.
In certain applications, carbon IS stronger than aluminum, and not just by a little bit. However, in others aluminum would be stronger.
Problem is however, just as there are more than one type of alloy for aluminum, there are many grades of carbon. Add in application, layup, resin, and environmental variables, and now all you have is a fraction of the necisarry information.
I for one feel that santa cruz do carbon very very well, and I feel their warranty is second to none. I don't however feel this way about most companies utilizing carbon today. I feel that a large majority of alloy bikes are superior to their carbon counterpart.

 @rezrov: Pinkbike should do a sealant test vid, the same tire, the same amount of sealant, the same size puncture. Because we all know that old Stans ad with the screws and nails in the tire is not the reality unless you have a whole bottle of stans in your tire. Which is another trick with sealant, fill the entire tire with the stuff and it will seal bigger holes.

 @rezrov: But why would people not take that one as given? In terms of strength relative to weight, carbon is the objectively superior material period. If done correctly, carbon is stronger than aluminium and you can build superior frames out of it. That's not a dogma, it's just material science and engineering.

When somebody shows me a random video made with a cell phone on uncle bucks farm, I'm a little skeptable.

 Carbon fibers spilling out when you get a puncture, sounds nice for the environment. Also can't wait to get poked from the fibers from handling the sealant and also the fibers poking out of the tire if a puncture did occur.

 I'm a little skeptical of the test conditions.

It looks like the grass from the freshly mowed lawn mixed with the sealant as a sort of aggregate (like a bacon strip) to help patch over the hole. It'd be interesting to see how well it sealed if the tire was ridden on pavement following the puncture.
