Bora™ Ultra™ wheels are the wheels designed for speed par excellence. Perfect aerodynamics and maximum power transmission combined with extraordinary lightness make them the benchmark wheels for leading racing professionals. The 50-mm rims are made from structural carbon which imparts great lightness and stiffness. The hubs are made from structural carbon of variable thickness, have spherical surfaces, feature Record™-class components with aluminium axle and a single body for freewheel and pawl carrier. The rear hub features an oversize aluminium flange on the right side which enhances the features of the G3™ spoking. Radial spoking and G3™ spoking are used on the front and rear wheels respectively. Nominal weight is just 1,305 g. Bora™ Ultra™ wheels are fitted with new quick releases with levers in cold-forged aluminium with two pivots for more balanced clamping.
