The power of aerodynamics.
In describing a racing bike wheel like Wind 55 DB, you start with aerodynamics: it's time to try out on your bike how a finished and optimised profile down to the finest detail is able to make the difference.The 55 mm full carbon unidirectional rim, a full 27 mm wide, is the result of an endless cycle of tests, wind tunnel analyses and laboratory finishing.
Then on the road, with the main objective of reducing the effect of side winds on the ride as much as possible.
And this is what you notice when you choose to race on Wind 55 DB: it cuts through the wind, guarantees stability and consequently very high average speeds without excess effort.
Completing this package id the 2-Way Fit, 19-mm internal channel, designed to offer the best support for tubeless tires and designed to best match the 25 and 28 mm sizes with the wide rim profile. Thanks to the Mo-Mag technology, no conversion will be necessary, the wheel is ready for use even without an inner tube.
If "Aerodynamics" is the first word that comes to mind to describe your new set of wheels, perhaps you should think of Wind as the first choice.
2-Way Fit - profile for tubeless and clincher. We have developed our 2-Way Fit technology to ensure the perfect compatibility of our tubeless rims with normal clincher types and tubes.
Rim Dynamic Balance (RDB) - The concept is simple and elegant: balance the weight of the gasket, with an item of similar weight placed on the exact opposite side.
Directionated Rim-Spoke Coupling (DRSC) - Exclusive rim/spoke coupling system. It allows the rim, spokes, nipples and hub to align properly with the same tensioning value in all areas.
Momag - A magnet and lots of ingenuity. This was what led to the patent for the well-tested “Mounting Magnet” system, or MoMag.
Anti-Rotation System - 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 centred
b) will remain in the position that have been studied in the wind tunnel tests to ensure the best aerodynamic penetration possible.
Fulcrum Identification Card (FIC) - 100% Handmade Quality - Right from its inception Fulcrum® has been marked by feature that continues to this day: that is to design, prototype and industrialise all the wheels characterised 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.
Traceability - A guarantee of quality
The keyword for their products is: traceable.
All this because, devoted to its mission, Fulcrum® demands the absolute perfection and safety for its customers.
AFS Axle System
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 our range.
Wide Rim Tech - This technical choice provides an ideal basis for 25/28mm tyres, the sizes currently popular.
This ensures stability, excellent handling and superior comfort.
Unrilled Rim Bed - No holes on the bridge connector means that the rim is uniform at every point, free from critical areas subject to stress.
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.

About The Brand
Since 2004, Fulcrum has developed wheels for bikes with a sole, constant objective in mind: to deliver the best performance that modern technology can offer.
A large part of this task is the responsibility of the R&D division engineering team in Italy. However, if you want to create even faster wheels, you cannot focus solely on test bench results, you also need to gain feedback from top riders and cycling fans worldwide.
And this is what Fulcrum has done: They race their bikes during lunch breaks or after work, test their wheels by pushing them to the max, fitting them to the bikes of world champions, listening to suggestions and comments from the world of racing and from their clients.
