It’s natural to point out that the design of the40 mm rimis the direct descendant of the 55 profile: all the solutions developed for the higher profile have been included here, in a less specialised version. So 40 mm,a light rim, created by the superposition of wide, modern unidirectional layers, with a pronounced profile (8 mm radius): innovative shapes, designed to blend with the tyre in a single element capable of eliminating turbulence, avoiding interrupting the flow of air that meets the wheel during the race. But 40 mm also means versatility, because it is generally one of the sizes most appreciated by those who do not want to overdo things, but want an excellent wheel uphill, stiff and snappy, precise when riding. The system is completed withaluminium hubs, designed at the CNC,which support 24 “straight pull” spokes, guaranteeing maximum overall rigidity, both in acceleration and when braking, without influences due to the asymmetric nature of the forces coming from the disc and cogset. Wind 40 DB is certainly the multi-purpose choice, with a strong focus on aerodynamics, to be fast, very fast, uphill, fast, very fast, on the flat, and just as much so downhill.
