Vittoria Pit Stop Inflating Sealant

Vittoria Pit Stop Inflating Sealant is a pressurized cylinder filled with compressed gas and a lightweight, polymer foam sealant. It is designed to deliver the sealant and between 80 to 90 psi of gas to inflate the tire and distribute the sealant into a 21-25c road tire. That is the ideal usage and expectation. In practice, expect less installed pressure as the tire volume increases and from any installation trouble. Pit Stop is not intended to fully inflate your tire, just get you well on your way with a puncture sealed. For those who run 85-90 psi, you may be just fine. Others will want to supplement with CO2 or a hand pump. The sealant is very effective for small punctures, less so on torn material. The polymer foam has been developed to work best with Vittoria's latex inner tubes- clincher or tubular.

When you have a flat tire you open your valve stem, push the nozzle on the Vittoria Pit Stop canister onto your valve stem, and press the canister towards the tire to release the compressed gas and the liquid foam sealant. Both substances shoot quickly into the tire under pressure. The gas inflates the tire, expanding it while allowing the foam sealant to quickly spread within the tube. Remove the canister then spin your tire for optimal distribution. The foam then dries quickly, sealing the hole and fixing the flat. Even 80 psi of air will get you rolling, making Pit Stop ideal for a racing triathlete since you can repair and inflate, quickly with no tools. In competition this may be enough to get to T2, if not a quick pop of CO2 will fill you up. For training road cyclists and triathletes, having CO2 or a small pump on hand to top off your tire is crucial, but Pit Stop saves you the hassle of removing your wheel and tire, and saves on CO2 and mini-pump strokes. There is no perfect solution, but Pit Stop can get you moving again quickly and efficiently and the sealant will help prevent further punctures.

We encourage you, despite the expense, to practice with a canister before you need to use one on the road or in an event. Variables such as rim profile, exposed valve length and space between spokes can make it tricky when you are hyped up with adrenaline, or on a narrow road on a freezing cold day. If you practice, you haven't wasted the Pit Stop, you have installed sealant. One note: the gas will likely escape faster than air overnight. If your tire seems to be flat the next day, re-inflate with air- not CO2- to normal pressure. This is actually the same process you experience when you inflate with CO2 on the road, so don't be put off by it. This is not an indication that the sealant has failed.

Initially, many thought this inflating sealant would be a single answer. But, like with many such hopes, in reality, the results seemed disappointing. However, when you take into account that Pit Stop does save you time, hassle, and seals small holes permanently, the reality is that this is a very good product that can be an event or ride saver. The sealant is light, distributes thoroughly and won't pool like a liquid product. Once sealed and inflated, your tire retains rotating balance. Pit Stop has saved many tubular tires from small puncture death. All in all, properly used and realistically approached, this is a great product that protects your investment.

It's helpful but carry a pump. They're so small and light now there's really no excuse. The sealant usually plugs the hole completely, but even you still have a slow leak you can limp home if you have a pump.

The design of the canister makes it VERY hard to get the sealant inside of the tire. Competitors (like Hutchinson) have a flexible tube to attach to the valve; you then push a separate trigger to release the sealant. With the Vittoria, you have to jam the entire canister onto the valve - tough to do with deep-section wheels. You've only got one shot to get it right; if you miss, the sealant doesn't get into the tire, and you're walking home.

Pros Convenient to carry

Cons Doesn't work when you need it

I have used this twice after getting flats on the road. The first time was pretty messy but I got enough in to be able to return home. It definitely would have helped to practice with it before having to use it on the road. The second time it worked great, still a little messy but I made it home and have put on another 400 miles on the same tire. I ride on tubulars and carry this with me on every ride. Great product for me.

Pros light weight, easy to carry on the road, effective

Cons can be a little messy to use

Used twice with the same result - it doesn't work. In both cases, I had a small cut (.25") which the sealant was unable to plug. Definitely would not recommend.

Pros great concept - CO2

80/20 results over the past year and half with this solution. I'm stoked to be able to ride tubulars everyday knowing i have this sealant with me. I don't run Stan's as the feel of the tire changes big-time. Pit-stop has saved me most of the time, but with larger punctures it's useless. Like most reviewers note, you have to carry extra CO2 as the cartridge doesn't do the job alone.

Pros Get to ride tubulars everyday

Cons Long canister, low Co2 volume

Used this product on a slow leak in a Vittoria CX tubular. Great results, no extra inflation needed and tire is in service with regular air inflation several weeks later.

Definitely a decent product if you only need to get back to your car AND your car is parked relatively close by -- say no farther than 10 miles or so.

But like the other reviewers mentioned, this product gives you enough latex sealant, however it DOES NOT provide enough air pressure for a tubular to be fully pressurized. therefore, take along a CO2 cartridge and you’ll be fine.

I had a similar result with my first use of Vittoria pit stop, it fixed the leak but there was no where neer enuf tire pressure and you’ll likely need to finish inflating the tire by other means. I used it on my 22mm Tubulars, so its not like it was too big of a tire. Still, very happy to avoid junking a near new tubular and will use this product again.

I had my first opportunity to use the Vittoria Pit-Stop on a ride today but it did not quite work out. The instructions seem simple enough but the end result was some (enough) foam sealant got in the tube but hardly any CO2. As a co-rider also had a can with him, I did this twice with same outcome, a sealed tubular with just a few pounds of pressure. A CO2 cartridge bailed me out and I was able to ride home. I still believe in the product and will order some more cans but you may wish to experiment with the Pit-Stop product in the friendly confines of you garage and not on a far away back road AND carry a CO2 cartridge along.
