Your days of changing tires on the side of the road could be over.

Tufo's Extreme Sealant is capable of filling slightly larger puncture holes than their standard sealant. Unlike the standard formulation, it is not designed for preventative use before a flat has occurred. Use only after a flat. Designed only for use with tires and tubes with Presta valves with removable valve cores. Remove the valve core and insert the sealant through the valve stem. One bottle seals approximately three punctures. 50ml, includes valve tool.

Works almost every time

I've been riding tufo tubulars almost exclusively on my road bikes for the past seven years. My friends often ask my why I'm not concerned about flats and the hassle of changing tires. This product is a big part of the answer.

I don't get that many flats with tubulars in the first place (particularly the Tufo Elite Ride), but on those rare occasions when I do, a third of a bottle of this stuff squirted into the tire by removing the valve core fixes between 80 and 90 percent of the flats. And most of the time when it doesn't full seal up the leak, it will at least keep enough pressure in the tire for me to finish my ride and change the tire in the comfort of my home or hotel.

Not totally sold.

I bought some Tufo tubular clinchers last summer, and while the weather was nice, didn't need to use this. Once the fall got rolling and the weather changed, I had a bunch of punctures, not all of which were sealed by this stuff. And a few that were sealed later blew out while riding. I know, I know, I should have changed tires before the weather got bad, but the tires are soooooo comfortable to ride on! I'd say use it, but don't totally count on it saving you. I have my winter tires on now. I'm not sure I'll go back to the Tufo setup in the summer.

Works great
by Don

This stuff is amazing. It's pretty rare that I get a puncture that can't be fixed with this sealant. And in most of those cases, the tire will still hold enough air to get me home.

Once the bottle is opened, the sealant tends to set pretty fast, so if you use half a bottle to fix a flat, the remaining sealant won't last more than another month or two without becoming hopelessly gummed up.

I usually bring a small finishing nail in my bag to push through the nozzle to make sure it allows the liquid to flow.

Its reliable. It saved my tire over 4times. Im sure there is no sealant better than this.

But If you use a latex tire, I recommend you use different sealant. It isnt made for a latex tire.

I had a very big glass cut on the tire. I did not think or my mechanic thought it would work on sealing the tire.

It did! And has been keeping the Tufo tire seal for the last 6 months now.

I continue to be amazed at how well this works at fixing punctures. I was riding down the shoulder of a local highway notorious for flat tires and, sure enough, I picked up a large construction staple through my tire (Tufo Elite Ride). Given the size of the thing and the fact I now had two large holes in my tire, I was sure I'd be pulling the tire off. But I decided to give the sealant a try anyway. After unclogging the nozzle (the one problem with using a bottle that's already been opened), I squirted about 15ml into the tire, replaced the valve core and added a just a little CO2 to give it a bit of firmness. Spun the tire around so the holes were at the bottom to allow the sealant to do its thing. After a minute or two, I filled the tire the rest of the way. To my amazement, the pressure held. That was a couple hundred miles ago and the tire is still holding pressure fine.
