Fulcrum Wind 75 DB C19 2-Way Fit AFS wheelset
Wind 75 is the choice for those who are looking for maximum speed
The Wind line is now complete with the 75 DB model, a high profile that allows Fulcrum engineers to express the full potential of research and development in the aerodynamic field.
The ultra aero profile makes this wheelset ideal for time trials, triathlon and, in general, for all situations in which aerodynamics counts and you pedal at high speeds.
The design challenge was to achieve high values of air penetration and speed without compromising, given the height of the profile, the stability and handling of the wheel. This result has been achieved thanks to careful wind tunnel studies that have given as output the new unidirectional carbon rim profile whose internal and external dimensions follow the dictates of the new trends: 27mm wide and 19mm channel.
The rim is 2-Way Fit™ , tubeless. It does not require any sealing tape, simplifying and lightening the coupling with the tires thanks to the Mo-Mag™ technology. The rim without holes is also more rigid and resistant.
The spokes are made of double thickness stainless steel, rounded straight head (the most aerodynamically advantageous choice) and the nipples are made of aluminum.
As far as the internal mechanics are concerned, sealed cartridge bearings have been chosen inside aluminium hubs both at the front and at the rear.

Tubeless technology was first used by the auto industry , then by motorcycles and now has reached the cycling industry. After its debut with mountain bikes the moment has come to "put it on the road", and that's what Fulcrum propose to do. They've developed 2-Way Fit™ technology to ensure the perfect compatibility of tubeless rims with normal clincher types and tubes. 2-Way Fit™ wheels are perfectly multipurpose for tackling every situation.
Thanks to a special impression in the valve area, the tubes are fitted with the maximum precision while keeping the tube perfectly stable inside the tyre. Housing the valve for tubeless tires is also risk-free, with the unquestionable advantage that there are never any air infiltrations caused by non-ideal positioning when fitting. The advantages are indisputable: the tests have highlighted an unique increase in smoothness. Because there is no tube, the friction caused by rubbing against the tyre is eliminated, while the perfect adherence of the tyre to the rim prevents the dispersion of energy.
Tubeless tires do not suffer from sudden deflation when punctured which is a great advantage in safety terms. There is also no risk of snake bites as there is no tube to rupture.
RDB™ Rim Dynamic Balance
The concept is simple and elegant: balance the weight of the gasket, with an item of similar weight placed on the exact opposite side.
For carbon bike wheels the principle is the same, but applied using a different technology. When making carbon bike rims, the pieces of carbon fabric are aligned in such a manner that the resulting rim is always balanced.
DRSC™ - Directionated Rim-Spoke Coupling
Exclusive rim/spoke coupling system. It allows the rim, spokes, nipples and hub to align properly with the same tensioning value in all areas.
What is MoMag™? A magnet and lots of ingenuity. This was what led to the patent for the well-tested “Mounting Magnet” system, or MoMag™. How does it work? The nipples, once inserted inside the rim via the valve hole, are “guided” to the point of connection with the spoke by means of the magnet. This simple but ingenious system makes it possible to have a wheel without holes on the upper bridge, but with spokes tensioned by traditional nipples! Advantages: No holes on the rim means that the rim is uniform at every point, free from stress points or zones of weakness and, for the clincher profiles no rim tape is required, to the benefit of weight reduction. The advantages are immediately clear: greater rim lifetime, greater resistance to fatigue, the possibility to give the spokes greater tension, and greater stiffness which, in terms of performance, mean greater reactivity and acceleration. But that’s not all. The advantages also include extremely quick and simple maintenance and spoke replacement. All to the benefit of cyclists who choose Fulcrum®.
This new system raises the concept of spoking to a new level of performance for road bike and triathlon wheels ( and mtb too).
The Fulcrum® engineers have redesigned the spokes and the hub housings to create a solid and unmoveable whole. The result is that the spokes:
a) will never lose their initial tension, thus keeping the wheel perfectly reactive and centered;
b) will remain in the position that have been studied in the wind tunnel tests to ensure the best aerodynamic penetration possible.
F.I.C. Fulcrum Identification Card - 100% Handmade quality
Right from its inception Fulcrum® has been marked by feature that continues to this day: that is to design, prototype and industrialize all the wheels characterized by the red “F”.
Indeed these take shape inside of the R&D, the leading-edge department that represents the beating heart of the Italian company.
Every single component of the wheel, the materials chosen and the technologies applied are the tangible result of the effort that Fulcrum® makes every day to give you maximum performance and reliability.
A guarantee of quality
The keyword for Fulcrum's products is: traceable.
If you find a little label attached to any Fulcrum® product, do not remove it. It will provide you a guarantee in case of an ascertained defectiveness of a production batch, and so the component needed or wheel will be traceable.
All this because, devoted to its mission, Fulcrum® demands the absolute perfection and safety for its customers.
AFS axle system™
The Axial Fixing System™ is the solution developed by Fulcrum® to fix the disc brake to the hub. The constraint granted by the butt area of the release mechanism, greater than in familiar standard ones, makes it possible to obtain greater structural rigidity and therefore more precise and powerful braking.
Rim Full Carbon technology
Full carbon Fulcrum® rims are built using combinations, developed in the laboratory, of different types of fibre, including UD and the famous 90-degree 3K of models at the top of Fulcrum's range.
To build them Fulcrum developed a special HTG (high transition grade) resin, whose glass transition point is at a higher temperature than any other fibre used in the bicycle industry. This gives incomparable performance when braking.
Wide Rim Tech
Fulcrum®’s R&D department, following requests from the competition circuit, has worked to create rims that are wider than before, about 4 mm or more than previously. This technical choice provides an ideal basis for 25/28mm tyres, the sizes currently popular.
This ensures stability, excellent handling and superior comfort.
Undrilled Rim Bed
No holes on the bridge connector means that the rim is uniform at every point, free from critical areas subject to stress.
The advantages are immediately clear: less weight, longer lasting rims, greater resistance to fatigue, the possibility of giving the spokes more tension and more stiffness which, in terms of performance, means improved responsiveness and acceleration.
Disc specific Rim
Fulcrum® is one of the first wheel manufacturers on the market to offer two completely different rim profiles from disc to conventional brake. So, no adaptation, but a rim conceived based on years of design experience. Not requiring a braking track, Fulcrum®’s R&D department designed a completely new profile, aimed at saving every single gram of weight and at improving aerodynamic efficiency. Its greater width makes it a perfect fit for tyres of 25/28 mm upwards.
