Fulcrum Racing 5 DB wheels are designed for endurance bikes. The reduced aerodynamic resistance and stiffness guaranteed by the low U-shaped profile of 24 mm make these wheels the ideal technical choice for tackling long distances without having to worry about unevenness, rain or wind, thus saving energy and improving overall comfort.The aluminium rim has a new 20 mm inner rim tape and the innovative 2-Way Fit system, which makes it easy to fit 25-28 mm tyres, with or without tubes._x000D_ Technologies_x000D_ 2-Way Fit allows the installation of tubeless or clincher tyres_x000D_ Anti-Rotation system increases spoke performance, thanks to the spoke/hub interface that keeps the spokes in the same position_x000D_ Axial Fixing System for greater structural rigidity and more precise and powerful braking_x000D_ Disc Specific Rim: The rim has been specially developed for disc braking._x000D_ Asymmetric Rim: Asymmetry of the rim has been studied to improve the rim tension, balancing the forces coming from the brakes and the cassette_x000D_ Specifications_x000D_ Tyre type: 2-Way Fit_x000D_ Diameter: 700cRim material : Aluminium_x000D_ Profile height: Low_x000D_ Rim height: 24 mm_x000D_ External width: 25 mm_x000D_ Internal width: 20 mm_x000D_ Brake system: Center Lock disc_x000D_ Axle: 12x100 mm (front) / 12x142 mm (rear)_x000D_ Number of spokes: 24 (front / rear)_x000D_ Spoke material: Stainless steel_x000D_ Spoke profile: Rounded, straight head_x000D_ Hub: Aluminium, aluminium flange (front / rear)_x000D_ Bearings : Sealed cartridge bearings_x000D_ Weight limit: 120 kg (bike and rider)_x000D_ Freewheel body: Shimano HG11Weight: 1660g (per pair)_x000D_ _x000D_ _x000D_ _x000D_ _x000D_
