The Specialized S-Works Turbo RapidAir 2Bliss TLR 700c Tyres with Deceuninck–Quick-Step were designed with some lofty goals in mind: Make the all-around fastest, lightest, and most puncture-resistant tires Specialized have 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 Specialized's World Tour teams—they’ve been racing and winning on them all season long. The new design came from years of in-house development and testing. It features the new, patent pending construction that smooths out road imperfections and keeps rolling resistance low, while Specialized's 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. All this adds up to a tyre that rolls faster than a tubular, grips better in the wet and dry, and has the same supple ride. And finally, the cross-woven Blackbelt™ breaker is cut-resistant, but in the chance you do get a puncture, the new sealant plugs holes almost instantly. RapidAir tyres install easily on the rim, and can be seated with just a floor pump.
