The all-new S-Works Turbo RapidAir is our ultimate race day tire. The most efficient, lightest, best handling, and durable tubeless tire we’ve ever made. The original RapidAir is the tire that broke the World Tour’s addiction to tubulars with Tour de France stage wins, Green Jerseys, and Monument victories. Coaxing more speed and a longer life from our fastest race-day tubeless tire was no easy feat.We knew we had an incredibly fast foundation – RapidAir’s unique construction. Instead of a traditional three-ply casing that masses material under the tread where it increases rolling resistance, the Rapid Air casing is just two plies that overlap at the side wall that not only rolls faster, but grips better as well, with a more supple contact patch. Elevating this already formidable performance is our all-new Gripton T2 compound - the fastest, most efficient compound we’ve ever created. We’ve combined this with the legendary grip of our Gripton T5 compound on the shoulders. With this dual compound a set of 26mm S-Works Turbo RapidAir 2BR tires saves two watts of rolling resistance over the previous tire and adds approximately 1000 kilometers of life to a set. Oh, did we mention they are lighter? Just 230grams in 26mm.As a tubeless tire, the new RapidAir has ‘leave the spare tube at home’ performance when combined with RapidAir sealant, but the protection doesn’t end there. With new hybrid-Kevlar Blackbelt protection under the tread, you’ve got 12% more puncture protection with lighter weight and more flexibility for a more supple ride.The new S-Works Rapid Air is also compatible with both hooked and hookless rims for the flexibility to ride the wheels and pressure you want. Our new Zylon reinforced beads also exceed hookless burst pressure standards by 200% for ultimate peace of mind. The win-win’s keep on coming with new RapidAir.
