Flat tires have a way of finding you at the worst possible moment—thirty miles from home, halfway through a group ride, or warming up before a race. Vittoria's Pit Stop Inflating Sealant handles both problems in a single canister, delivering pressurized gas to inflate your tire while simultaneously injecting a polymer foam sealant to plug the hole that caused the flat in the first place. You're not just getting air; you're getting a repair.

The 75ml canister pumps enough pressure to inflate a 21-28mm road tire to approximately 6 bar, which translates to around 87 PSI for clinchers or up to 94 PSI for tubulars. That's rideable pressure for most road setups, though you may want to top off with a mini pump or CO2 if you're running higher pressures. The foam formula works across tube types—butyl, latex, and tubeless tires all respond to the sealant—which means you can carry one solution regardless of your setup.

Application takes seconds: remove the valve core if running tubeless, position the valve at twelve o'clock, attach the nozzle, and discharge the canister. The foam spreads as the tire inflates, coating the interior surface and sealing small punctures as it expands. Once sealed, spin the wheel a few times to distribute the sealant evenly. Vittoria says the foam remains active inside the tire for up to three months, continuing to protect against subsequent punctures during that window.... Read More
