The “Plus” world crosses over to the road. With the Speed 25+ Fulcrum redefines the concepts of precision and lightness. Following in the footsteps of the Red Zone Carbon+, the Speed 25 now take on the plus moniker, indicating the pinnacle of Fulcrum’s range, becoming the lightest low profile option for disc brakes ever produced.

Inspired on the Racing Light XLR, the Speed 25+ are the perfect choice both for steep alpine climbs and for long distances, thanks to the safe and precise ride feel that only low profile wheels can provide. Compared to the Speed 25 the weight has been dropped down to 1270 grams and they integrate the best Fulcrum technologies, for an astounding set of wheels in terms of lightness and handling, without compromising reliability (ASTM 1 – System weight limit: 120kg).

Technologies of the Fulcrum Speed 25 plus wheels

2-Way Fit™

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 we propose to do.

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 Fit™road 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.

Cult™ - Ceramic Ultimate Level Technology™

Behind this project is the exclusiveness of Cronitect® steel, using “Advanced by FAG” technology by Schaeffler Group employed for the bearing races. This steel is resistent to the corrosion of the highest level until the point that no grease is necessary for lubrication, maybe just a small amount of oil.

The top quality ceramic balls, thanks to the absence of lubricating grease and the precision machine of the cup and cone technology, allow to reduce the friction coefficient drastically and then increase the smoothness of triathlon and road bike wheels by as much as 9 times compared to standard bearings. An outstanding result achieved by using cutting-edge technologies in the field of materials processing.

MoMag™

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 wheels without holes on the upper bridge, but with spokes tensioned by traditional nipples!

The 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.

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.

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.

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.
