Description of Fulcrum Speed 40C Carbon Wheelset Clincher

Clincher tyres, 40 mm deep profile, 17mm inner width, 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 roadbike lovers who will not settle for anything but the best.
But still this is not a specialist set of fragile lightweight design wheels, indeed Speed 40 C offers top performance in a wide variety of contexts: Fulcrum engineers 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 to the rear oversize flange and the Two-to-one™ spoke pattern - as a basis, Fulcrum has 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 optimized 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 wheels 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.

Special properties of the Fulcrum Speed 40C Carbon wheelset:

Rims: 40 mm deep "Twill" carbon rims with a 17C cross section: this wider base provides more grip, more comfort and a superior handling. The rims are made from unidirectional carbon, among the best-performing currently available on the market. Their brake tracks are featuring AC3 - All Conditions Carbon technology. It uses micro laser incisions on the surface to eliminate resins and to achieve better roughness.

Aerodynamics: The wide and rounded profile reduces the friction coefficient.

Nipples: The nipples are specially shaped to facilitate the assembly process and to stay in place without the addition of any other cushioning material.

Rear hub with oversize flange: Carbon hub with oversize aluminum flange and Two-to-One™ technology: the doubling of the spokes on the cassette side provides greater torsional stiffness and therefore a greater reactivity at each pedal stroke. This means greater efficiency in the transmission of power to the wheel.

Front hub: The front hub features a carbon body, aluminium flanges and small dimensions so it is extra light. Smoothness is ensured by the famous USB™ ceramic bearings.

Spokes: This setup provides aluminium aero spokes. They ensure optimal rigidity and aerodynamics.

P.E.O. (Plasma Electrolytic Oxidation) coated freehub body: The freehub body for Shimano-SRAM will be submitted to Plasma Electrolytic Oxidation treatment in the laboratory. Despite the thickness of the material being reduced to the minimum, the duration and strength are maintained with the benefit of a lower weight.

Technologies of the Fulcrum Speed 40C Carbon wheelset

2:1 Two-to-One™: On the rear wheel the number of spokes on the drive side is twice as much that of the opposite side. Greater stability of the wheel thanks to the perfect balance between the spoke tensions - greater torsional stiffness and greater reactivity.

Anti-rotation System™: Keeps the spokes in the position of maximum aerodynamic penetration.

MoMag™: Allows the external profile of the rim to be free of holes - increases structural resistance - makes a rim tape unnecessary and reduces the weight of the wheel.

USB™ ceramic bearings: Reduce the friction between ball and bearing, increase smoothness, reduce weight and maintain performance over time, thanks to the absence of corrosion.

Bike24: Übersetzung: Es sieht toll aus, es ist geschmeidig, es hat eine gute Bremswirkung, und ich benutze es immer noch, um die Berge in dieser gebirgigen Umgebung in Taiwan zu bezwingen.
This is my first Carbon Wheelset, and off course Fulcrum was only option for me. Best price online from Bike24, wheels is Excellent, smooth, lightweight and AWESOME looking wheels, excellent for any terrain, hills, flat stages, braking is very very good, better then my Alu Fulcrum Zero's, absolutely love them !!!
When buying carbon clincher wheels, I was deciding between Fulcrum Speed 40C (height profile 40mm, weight 1402g) and Fulcrum Racing Zero Carbon (height profile 30mm, weight 1340g by specs - 1370g after weighing someone on bike24). Whatever, both wheelsets are toxic to race wins. Exelent rolling - USB ceramic bearings, top brake performance AC3 - also in raining weather, I would not waste words on the quality of carbon. In the end I chose Fulcrum Speed 40C, because they have 40mm rim height. They are not cheap, but the quality count. Highly recommend!
