Fulcrum Speed 57 C23 Team CL Disc Tubeless road wheel set

Speed Team is a product that channels technical perfection and a bold design. An evolution of the Speed 57, it retains the same technical characteristics but with a new feature that makes the difference: the freewheel body lightened with USB™ (Ultra Smooth Bearings) ceramic bearings. A racing solution that further increases smoothness and efficiency, eliminating friction and guaranteeing an unparalleled riding feel.

Technologies:

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.

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™:
- When you push on the pedals, the rotational force on the sprocket induces a slackening of the freewheel spokes with a consequent loss of rim tension.
- This results in undesirable flex of the whole wheel and an unavoidable loss of energy. Fulcrum® has solved this classic cycling problem with its 2:1 Two-to-One™ Spoke Ratio patent, by doubling the spokes in the critical zones.

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™.

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.

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.

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.
