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.

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.

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.

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.

Reliable, durable puncture sealant for tubular tires

I love my tubular tires (I generally ride Tufo general-purpose road tires) but I hate getting punctures - a common experience on the torn-up, pothole-laced, debris-ridden streets of Norfolk, Virginia. I get quite a few nicks from discarded metal and fasteners that wind up on the streets, or unfinished bits of metal and concrete on the road surface. Tufo extreme sealant quickly and reliably seals these punctures. The product is easy to use - just pour it in and you are ready to go in an instant. The repairs made with this product last many, many months. (I commute by bicycle to work every day. I generally cover about 10 miles per day communiting and do another 20 or so a week for recreation.) I have repaired multiple punctures in the same tire with this sealant. Given the cost of a new set of tires, this tire-saver is a cost effective solution. I probably would have given up my tubulars if I didn't have such a ready solution to flats. I highly recommend this product.

But, hey, Tufo, if it saves you and me money, I have never once used the attached valve tool.

The best sealant for Tufo and Clement tubulars.

Whenever I set up a fresh set of Clement PDX, MXP, etc tubulars, I use Tufo extreme sealant. Other sealants will dry out and leave Stanimals inside your tire, but Tufo extreme seems to stay liquid longer.

A solid mass of coagulated rubber

I've foolishly bought the extreme sealant 4 times. Each time it turns solid, even if unopened.. Yesterday, I flatted on a very small stone. The unopened sealant was coagulated, but I was able to squeeze a little in the tire. It held about 15-20 psi. Had to call for a rescue car. The white Tufo sealant is much more dependable. Don't waste your money. Pre-seal your tubulars with Green Slime (yes, it works well) or the white Tufo sealant.

I had a flat after having this bottle for a few months but it was solid. Two lessons learned (1) check the bottle to make sure it is not solid before heading out for a 6-hour ride, and (2) don't buy this sealant again.

I wish I could give this product a positive review, but unfortunately I can't. I purchase a bottle and stuck in my saddle bag. A month later I got a flat, and figured I would give this stuff a try, but the liquid in the bottle was solid as a brick. This was a unopened factory sealed bottle.

Worse part of this experience was I had to call my ex-wife to give me a ride home.

To prevent premature sealant solidification in the bottle simply squeeze all the air out of the bottle before replacing the cap.

I used the extreme sealant after trying the other guy's stuff and found it really worked on the large gashes I got in my cx tufo tires. I holds in normal cx conditions but gave out at 65 psi on the road.

With the price of some tubulars reaching in upwards of $100.00 investing in a bottle of this sealant is a win win for anyone. You might just save that very expensive tire it takes minutes to fix a tire! I've fixed three tires this season. Oh yeah and I did it while on a ride. In a few minutes I was back on the road. If you ride tubulars your doing yourself an injustice not trying this.

Good stuff, but some problems with shelf-life
rating
by LA Cyclist

Pros Fast acting. Heavier solids work effectively against larger holes. Holds higher pressure. Included valve tool is wonderful.

Cons Solidifies in bottle over time, and no indication of shelf lifeexpirationuse by date is given on the bottle. Nozzle prone to clogs after use. Long bottle awkward fit for shorter seat bags. Will damage the finish of wooden floors.

I usually ride Tufo S33 Specials at 120 psi. They've been great, so great that when I finally did get a flat, most of the sealant (which I bought 6 months previously) had solidified inside the tube. There was still enough to do an effective job - thanks, Tufo - and the tire's still holding 120 psi after another 250 miles.

Exposure to air will solidify this stuff pretty quickly. While repairing on the road, I injected some, set the bottle aside, and inflated the tire. When I found I needed a little bit more, the stuff still inside the nozzle had solidified. Fortunately, the wire used to tie the valve tool to the bottle came in handy at reaming the nozzle out.

So I like this product, but I'd like it more if there were some sort of expiration date, which is the reason for the two stars' value rating. My next tube I'll probably seal in a zip-lock bag to add another layer of protection.

Finally, be careful of spilling this stuff on hardwood floors. If so, clean the floor immediately. Should you keep your bike indoors, put some sort of drop cloth under the repaired tire. I spilled some on a hardwood floor, found it soon afterwards, and it had already stripped the finish. That's my fault, not Tufo's, but worth knowing.

I just got a glass puncture today on my Conti Competition 700x23 (rear) and this stuff sealed the hole nicely. It squirted out a bit during inflation (as expected) and subsequent spinning of the tire but eventually held and I was able to continue my ride. I had 50 miles left and had only brought one CO2 cartridge but that and this sealant were enough to save the ride and apparently the tire. I won't race on it with this sealant in it but I will certainly continue to train on it as long as the tread allows.
