Airlock Presta Valve Tube Size:29 x 1.75-2.4 at the bike parkWe're not afraid to say itour Airlock Presta Valve Tubes are the best performing, self sealing bicycle tubes available. That's because they feature our powerful Airlock sealant that coats the tube for permanent protection against punctures. Not only this, but the sealant is designed to work continuously in order to prevent slow leaks from occurring, so erring complete catastrophe, you won't have to worry about flatting when you're riding over debris.
