Fulcrum Speed 42 DB Team WF C23 AFS wheelset 2025

There is a unique feeling shared by both professionals and amateurs alike: the quickening heart rate before the start of a race, energy flowing through the veins and the urge to push further

The new Fulcrum Speed Team are born to celebrate the spirit of competition and the adrenalin of racing, which have always defined the essence of Fulcrum. Speed Team is a wheel that embodies technical perfection and bold design. An evolution of the Speed 42, it maintains the same technical specifications, but with one crucial difference: a lighter freewheel body with USB™ (Ultra Smooth Bearings) ceramic bearings. A racing solution that increases smoothness and efficiency even further, eliminating friction and guaranteeing an unrivalled ride feel. Speed Team is a product that embodies technical perfection and bold design. An evolution of the Speed 42 and 57, it retains the same technical features but with an innovation that makes all the difference: the lightened freewheel body with USB™ ceramic bearings (Ultra Smooth Bearings). A racing solution that further enhances smoothness and efficiency, reducing friction to zero and guaranteeing an unrivalled riding feel. If the technical soul of the Speed Team is based on innovation, the design is an ode to competition. The new oversize logo, with a metallic effect, represents energy, boldness and strength. A graphic that wants to catch the eye and tell an unfiltered story of passion for the race, whether it is a granfondo or the stage of a grand tour. This iconic aesthetic celebrates the emotional connection between those who run for a living and those who live to run.

Technologies

2-Way Fit™
2-Way Fit™ profile for tubeless and clincher.
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 they propose to do. They 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.

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.

2:1 Two-to-One Spoke Ratio™ - Disc Brake
A system that is as simple as it is effective, the result of the ingenuity of Fulcrum® engineers and attentive observation of the results of the tests performed on the wheels on a daily basis. These tests made it possible to understand that the forces that act on the sides of the wheels, and therefore on the spokes, are extremely different; but what’s more, the differences between the front and rear wheels are also evident and significant. The front wheel, in fact, has to remain stable even during braking of the disk on the left side, and the rear wheel, in addition to the sprocket set, has to compensate for the traction of the force on the chain side.

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.

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.

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.

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.
