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.
