Tubular tires are awesome, until you get a flat and feel like leaving your wheels on the side of the road and carrying your bike home on your back. Vittoria's Pit-Stop Road Racing and Tire Repair Kit will save your punctured bacon, though, by plugging any holes with fast-acting latex foam that will seal your tubes or tires for miles and miles. You can even use it preemptively to prevent flats, if you want. The canister works with both Presta and Schrader valves, and the foam is lighter than traditional liquid sealant, so it won't slow you down when you throw it in seat bag or strap it to a seat tube.
