Vittoria Pit Stop is a pressurized cylinder filled with compressed gas and polymer foam sealant. Think of it as fit a flat for a bicycle tire. Reports are that it works quite well and much better that other products available. When you have a flat tire you simply open your valve stem, press the nozzle on the Vittoria Pit Stop canister onto your valve stem and press toward the tire to release the compressed gas and the liquid foam sealant. Both substances shoot into the tire under pressure. The gas inflates the tire while the foam sealant flows into the puncture and instantly dries, sealing the hole and fixing the flat. It is ideal for triathletes since you can fit a flat quickly with no tools. It also eliminates the need to carry, tubes, tires levers, a pump, patch kit, and CO2s.

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 youll 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 youll 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.
