Galinis dviračio ratas Fulcrum Speed 25 DB 2WF C21 AFS HH12/142 USB

Developed with a precise objective: maximum performance uphill. Fulcrum’s new Speed 25 marry lightness and handling in a low profile wheel, which is perfect to conquer peaks and enjoy the downhills, thanks to the application of Fulcrum’s premier technologies. The inspiration for the development of the Speed 25 were the race-winning Racing Light XLR. An extremely successful and popular wheel both with the general public and with the professional racers who used them for mountain stages. The Speed 25 have a 26 mm profile, which is symmetrical on the front and asymmetrical on the rear, to optimise the sweet spot between lightness and aerodynamics. With an official weight of only 1,285 grams, they are the ideal wheel for cyclists looking to post their best times uphill, but also for ultra-cyclists who have to deal with adverse weather conditions and want a stable and reliable wheel even in strong gusts of wind. The Speed 25 have been developed in a disc-brake version, with an inner rim width of 21mm and Fulcrum’s proprietary technologies, MoMag and DIMF. The minimally-designed hubs use USB ceramic bearings. Lightness, handling and smoothness are the key aspects of the wheels’ performance.

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.

MOMAG: A magnet and lots of ingenuity. This was what led to the patent for the well-tested “Mounting Magnet” system, or MoMag.

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.

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.

PLASMA FREEHUB:The Plasma treatment makes the aluminium especially hard and resistant to surface abrasion and wear. This has allowed thickness of materials to be reduced to a minimum, achieving advantages of lighter weight, while maintaining lifespan and reliability.

USB CERAMIC ULTRA SMOOTH BEARINGS: Fulcrum has a long-standing reputation for the extremely high performance of its hubs in terms of smoothness and reliability. In fact, all the projects are entirely developed in our R&D department and we have put obsessive care into taking care of every detail. The hubs with USB ceramic bearings (Ultra Smooth Bearings) further enhance the triathlon and road bike wheels’ smoothness and reduce weight and the need for maintenance.

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.

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