When we began developing the new S-Works Turbo RapidAir tires with Deceuninck–Quick-Step, they had some hefty goals for us: Make the all-around fastest, lightest, and most puncture-resistant tires we’ve ever made. And of course, they had to have the ride quality of tubulars. Sure, it wasn't easy, but one ride on them and you'll never want to be on anything else. Just ask our World Tour teams—no more tubulars for them.The new design came from years of in-house development and testing. It features a flexible center construction that smooths out road imperfections and keeps rolling resistance low, while our exclusive GRIPTON® compound leads the industry in both speed and cornering grip. Next up, the wide tread design and stable sidewalls deliver precise handling while diving hard into corners. And finally, the cross-woven Blackbelt™ breaker is cut-resistant, but in the chance you do get a puncture, our new sealant plugs holes almost instantly.But what about set-up? RapidAir tires seat easily on any tubeless-ready rim, and they can often be seated with just a floor pump.Read Less Casing: 120 TPI Bead: foldable Butyl wrapped bead = 2Bliss Ready Compound: GRIPTON® Flat Protection: BlackBelt 700x26mm, PSI 85-100 Approximate Weight: 240g 700x30mm, PSI 75–90, 305g
