SPEED 40C Clincher tyres, 40 mm, 17C rim, Full-carbon Twill… what more could you want from a racing bicycle wheel? Speed 40C represents the pinnacle of wheel design, it is a dream set of wheels for true bicycle lovers who will not settle for anything but the best.This is not a specialist set of wheels, indeed SPEED 40 C offers top performance in a wide variety of contexts: we like to think of this versatile wheel as an ideal half-way solution that does not take away anything but offers a great deal.Using the solid and ultra-responsive structure - made possible thanks tot he rear oversize flange and the Two-to-one™ spoke pattern - as a basis, we created an all-new rim, fibre after fibre, to enhance performance in two crucial moments of a race: acceleration and braking, which has now been optimised for any weather condition thanks to the use of AC3™ technology.SPEED 40C is designed for those seeking a winning set of wheels, built with the same technology chosen for the World Tour but even more functional thanks to the clincher tyre. The 40 mm profile makes the most of aerodynamics and the flywheel effect while remaining balanced, easy to handle and quick on the climbs thanks to a balanced and reactive rim.
