EXCLUSIVE GEOMETRY OF THE POLYGONAL RIM: Allows for an elastic rim, which is both comfortable and extremely responsive at the same time.REAR RIM WITH AN ASYMMETRICAL DRILLING: Allows for a perfect alignment of the nipples and hub for better spoke tension, leaving no weak points.MILLED, LOW-PROFILE RIM: Reduces the peripheral weight of the rim, and makes the wheel responsive and fast, especially in up-hill rides.STRAIGHT-HEAD STEEL SPOKES IN VARIABLE SECTIONS: Maximum wheel torsional stiffness. Spoke tension is maintained and guaranteed performance with the best aerodynamics. Stability even at high speeds.CARBON FIBRE HUB BODY: High degree of lateral stiffness - reduces the weight to the minimum.AND CONE BEARINGS: easy ball/bearing adjustment - reduces possible ball/bearing play - precision operation - maintains performance over time.OVERSIZED FLANGE: Increases the torsional stiffness, increasing reactivity at each change of pace of the cyclist.ALUMINIUM AXLE: Reduces the weight of the wheel.QUICK RELEASE: Steel spine and eccentric, lever with drill lightening and aluminum die. Eccentric-closure system allows cyclist to modulate the pressure necessary for heightened sensitivity to find the proper closure for the block. Easy to use, with a material resistant to wear and tear, rust, and pressure.
