The union between attention to aerodynamics and versatility creates Fulcrum Wind 40 Disc Brake.
It is natural to underline how the design of the 40 mm rim is the direct descendant of the 55 profile: all the solutions developed for the higher profile have been reported here, in a less specialized version.
40 mm profile therefore for a light rim, created by the superposition of layers of modern unidirectional carbon, wide and with a pronounced nose (8 mm radius): innovative shapes, designed to merge with the tire in a single element capable of eliminating turbulence, avoiding interrupting the flow of air that meets the wheel during the ride.
But Fulcrum Wind 40 DB also means versatility, because it is generally one of the heights most appreciated by those who do not want to overbalance, but have the possibility of having an excellent wheel for climbing, rigid and snappy, precise when driving.

The system is completed with CNC-designed aluminum hubs, which support 24 "straight pull" spokes, guaranteeing maximum overall stiffness both during acceleration and braking, without influences due to the asymmetric nature of the forces coming from the disc and sprocket cassette.
Fulcrum Wind 40 DB is certainly the multi-purpose choice, with a strong focus on aerodynamics , to be fast, very, uphill, fast, very, on the flat, and equally downhill.

2-WAY FIT
2-Way Fit profile for tubeless and clincher.
Tubeless technology was adopted in the automotive sector, then in the motorcycle sector and finally in cycling. After the debut with the mountain bike, it is time to "put it on the road" by offering new types of wheels for racing bikes. We have thus developed the 2-Way Fit technology to ensure perfect compatibility of our tubeless rims even with normal tires and inner tubes. The 2-Way Fit wheels are perfectly versatile to tackle any situation.
Thanks to a particular footprint in the valve area, the assembly of the inner tubes takes place with the utmost precision, keeping the chamber perfectly stable inside the clincher. Even the valve for tubeless tires is housed without risk, with the undoubted advantage that there are never air infiltrations due to non-optimal positioning at the time of assembly.

Dynamic rim balancing
The concept is as simple as it is ingenious: balance the mass of the rim joint with a mass of equal value positioned exactly on the opposite side.

Rim-spoke directional coupling .
The exclusive rim/spoke coupling system allows you to align the rim, spokes, nipples and hub by distributing the same tension value at each point, thus managing to eliminate the most critical areas.
