Calitate înaltă SET ROTI FULCRUM RACING ZERO CARBON COMPETIZIONE DB C19 2WF AFS 12x100mm 12x142mm Shimano

Fulcrum Racing Zero Carbon Competizione DB wheels follow the trend towards minimalism in terms of design. Equipped with CULT bearings, they are smoother and lighter than their big sisters. The carbon rim has a double unidirectional carbon finish with ARC Technology reinforcements with Twill carbon finish near the nipple area. This solution allows the rim to be reinforced in a unique way even when viewed from a distance. The profile retains the characteristics of the original version with a height of 30 mm, a 19 mm channel and, above all, 2-Way Fit technology. Technologies 2-Way Fit allows the installation of classic tyres such as tubeless tyres. CULT (Ceramic Ultimate Level Technology): Steel used for the ball raceways. Its resistance to corrosion is such that it does not require grease for lubrication, but only a little oil. Rim Dynamic Balance: Balancing the mass of the rim joint or weld with a mass of the same value, placed opposite. 2:1 Two-to-One: Multiplication by 2 of the number of spokes in critical areas to avoid spoke tension drop. Anti-Rotation System to prevent the spokes from turning and losing tension Axial Fixing System (AFS): Solution to fix the brake disc to the hub. The stress granted by the stop zone of the release mechanism, which is greater than in known standard mechanisms, makes it possible to obtain greater structural rigidity and therefore more precise and powerful braking. Wide Rim Tech: Approximately 4 mm wider rim to provide an ideal support base for 25/28 mm tyres. Undrilled Rim Bed: No drilling on the top wall for a more homogeneous rim without critical points High Strength Aluminium: Best 6082 aluminium alloy with T6 pre-aging treatment that stabilises the alloy and provides optimum durability and reliability characteristics. Carbon hubs: 90° braided fibre to better balance the torsional forces in play during pedalling Plasma Freehub: Plasma treatment of the cassette body makes the aluminium particularly hard and abrasion-resistant Oversized flange: For better transmission of watts to the ground without dispersion Features Type of tyre: Tubeless / Classic tyres Wheel diameter: 28″.
