The Fulcrum engineers have redesigned the spokes and the hub housings to create a solid and unmoveable whole. The result is that the spokes will never lose their initial tension, thus keeping the wheel perfectly reactive and centred. The spokes will remain in the position that has been studied in the wind tunnel tests to ensure the best aerodynamic penetration possible. Fulcrum Identification Card (F.I.C.) 100% Handmade Quality: Right from its inception Fulcrum has been marked by a feature that continues to this day: that is to design, prototype and industrialise all the wheels characterised by the red “F”. Indeed these take shape inside of the R&D, the leading-edge department that represents the beating heart of the Italian company. Every single component of the wheel, the materials chosen and the technologies applied are the tangible result of the effort that Fulcrum makes every day to give you maximum performance and reliability. AFS Axle System: The Axial Fixing System is the solution developed by Fulcrum to fix the disc brake to the hub. The constraint granted by the butt area of the release mechanism, greater than in familiar standard ones, makes it possible to obtain greater structural rigidity and therefore more precise and powerful braking. Asymmetric Rim: The asymmetry is designed to improve rim tension, balancing the forces from brakes and sprocket cassette. 2-Way Fit Ready: This procedure transforms Racing 5 DB wheels (designed to be used with a clincher tyre and inner tube) into tubeless ready wheels (i.e. with a Tubeless Easy tyre, no inner tube and compulsory use of a sealant liquid). Use of tubeless and tubeless ready tyres is forbidden on 2-way Fit Ready rims without official Fulcrum 2-way Fit Ready adhesive tape. This model comes with tubeless type installed and valves included.

Fulcrum Racing 700 Disc WheelsetDeveloped to help you to achieve your personal cycling ambitions, this road bike wheelset offers quality and performance on every mile. This includes the Asymmetric Rim profile, which increases stiffness, the AFS Axle system that provides better disc brake stability and the 2-Way Fit that allows the use of a Tubeless Tyre setup with this wheelset.AFS Axle SystemAFS is the disc rotor mount solution developed by Fulcrum to fix the disc brake to the hub. The stability and consistency granted by the end area of the hub provide more performance than in standard rotor mounts. This makes it possible to achieve greater structural stiffness and creates more precise and powerful braking performance.Disc Brake Specific RimAs a disc brake setup does not require a braking track, Fulcrum designed a completely new rim profile, which successfully saves every single gram of weight without sacrificing structural integrity and improves aerodynamic efficiency.Asymmetric Rim ProfileThe Asymmetric design effectively improves rim tension and balances the forces from disc brakes and modern sprocket cassette ratios.Monoblock Hub for DiscTo reduce the loss of braking power from flex and torque of the central tube between the two sides of the hub, a special one-piece system has been devised with internal stiffening ribs, which eliminate flexing within the hub shell, increasing braking power and consistency.2 Way-Fit Ready (Road)This technology ensures that the wheels can be converted to use a tubeless tyre system and if preferred, you can use standard tubes also.One Hub Fits AllThis solution meets the demands of the need to be able to fit your wheels to the various axle/dropout standards on the market. This system makes changing the dropout adaptors simple and efficient.
