Polkupyörän takapyörä Fulcrum Wind 57 DB 2WF C23 AFS HH12/142

Designed with the aim of balancing performance and comfort, the Wind 57 guarantee fluid handling and versatility. In fact the new wheels are not solely for road use, as they can also handle light off-road riding too (ASTM category 2), so that your fun can extend beyond traffic-congested roads. This project embraces the various ways that people are using road bikes lately. From the range-topping Speed family, in terms of performance, the Wind 57 inherit many of Fulcrum’s proprietary technologies, to offer a superior ride feel compared to the previous generation. Handling has been improved by 22% and reactivity by +10%* on these versatile and comfortable wheels, making them perfect for modern cyclists. Amongst the most evident changes there are the rims whose height has been raised to 57 mm, with an inner rim channel of 23 mm. The graphics have been completely redesigned too and reflect the new Form Function Fulcrum brand identity, with a minimal and at the same time refined design, which includes new icons that provide all the product’s technical information.

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.

DRSC - DIRECTIONAL 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.

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.

CUP & CONE: The cup-and-cone bearing differs from the classic cartridge bearing because it works in perfect alignment with the forces involved, weight and thrust from the frame, as the bearings run in a race positioned directly opposing these forces. The adjusting ring lets you pre-load the bearing, so you can eliminate side-to-side play and have optimum adjustment once the wheel is mounted on the frame.

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.

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.

ASYMMETRIC RIM: The asymmetry is designed to improve rim tension, balancing the forces from brakes and sprocket cassette.

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.

WIDE RIM TECH: Fulcrum’s Research and Development 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.
