Dviračio ratų komplektas Fulcrum Wind 75 DB 2WF C19 AFS front HH12 - rear HH12/142 with DRP

The 75 DB model completes the WIND range. This high profile wheel is the best expression of all the aerodynamic research and development carried out by our engineers. The ultra-aero profile makes it the ideal wheel for time trials, triathlons and all situations where aerodynamics make the difference and you’re pedalling at high speeds. The challenge of the project was focused on achieving high air penetration and speed numbers, without compromising the wheel’s stability and handling, despite the height of the profile. This was achieved with thorough wind tunnel testing, that resulted in a new profile of the unidirectional carbon rim, whose internal and external dimensions are in line with current trends: rim width 27 mm and channel width 19 mm. The rim is 2-WAY FIT, tubeless from the outset. It doesn’t need any tape for sealing, simplifying and lightening the tyre-rim pairing, thanks to the rim machining with Mo-Mag technology. The rim is also stiffer and more resistant without holes. The spokes are double butted, rounded and straight pull (the best aerodynamic shape) and the nipples are in aluminium. As far as the internals are concerned, we have chosen sealed cartridge bearings housed in aluminium hubs, for both the front and rear wheel. Two extremely important aspects for the riders are the exceptional price/performance ratio, that makes this fast wheel more accessible compared to the SPEED range, and the possibility of buying only the rear wheel. The WIND 75 are the best choice for those looking for maximum speed and an access point to Fulcrum’s carbon range. This beautifully designed wheelset, which will make your bike unique, are a precious ally when every second counts and the epitome of #FULCRUMFAST.

TECHNOLOGY

2-WAY FIT (ROAD): We have developed our 2-Way Fit technology to ensure the perfect compatibility of our tubeless rims with normal clincher types and tubes. 2-Way Fitroad bike 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 tyres is also risk-free, with the unquestionable advantage that there are never any air infiltrations caused by non-ideal positioning when fitting.

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 top models, this is obtained by a special operation on the section of the rim opposite the rim joint. For entry-level models, Dynamic Balance is obtained by using two oversized spokes in the section opposite the joint. The result is a wheel with perfectly balanced rotational dynamics.

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.

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: 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 centred 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 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. 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.

TRACEABILITY: A guarantee of quality. The keyword for our 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.

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.

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. To build them we 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.

DISC SPECIFIC RIM: compatible only with disc brakes

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.
