Fulcrum Racing Zero Carbon DB Wheelset

More Information
Brand	Fulcrum
Colour	Black
Wheel Size	700c

Fulcrum is a subsidiary brand of Campagnolo that produces Alloy and Carbon wheels for road and mountain bikes. Initially developed so that Campagnolo could produce wheels compatible with brake and drive systems by Shimano and SRAM, allowing Campagnolo to retain its exclusivity. However Fulcrum still produce Campagnolo-compatible wheels.

By respecting the fundamental points of the Racing Zero family, and interpreting the world of disc brakes, the Fulcrum R&D division has successfully risen to a decidedly complex challenge: that evolving while respecting history to make an absolutely mind-blowing product.

It all starts with the base concept: carbon and aluminum together to create a unique combination, introduced on her sister for traditional brakes, to enhance reactivity and stiffness to the total advantage of a precise, decisive ride.

The 30 mm rim profile helps with lightness uphill, while the wide 19 mm well creates the ideal contact surface for shifting limits to unseen levels. Innovative technologies, such as the new ARC covering that creates an elastic reinforcement on the spoke eyelet, help in this direction. Unparalleled performance, technology, and innovation.

Racing Zero Carbon DB comes into its own on every double-figure uphill gradient, when power transmission is a must.

It also delivers downhill, because the wide rim and aluminum spoke support help to make you feel you can dare that extra meter.

Racing Zero Carbon DB adapts with style and character to the most diverse of contexts, establishing itself as the absolute benchmark for multi-purpose wheels.

Technology

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 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.

RDB™ Rim Dynamic Balance

The concept is simple and elegant: balance the weight of the gasket, with an item of similar weight placed on the exact opposite side.

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.

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™.

Anti-Rotation System™

This new system raises the concept of spoking to a new level of performance for road bike and triathlon wheels ( and mtb too)

The Fulcrum® engineers have redesigned the spokes and the hub housings to create a solid and unmoveable whole. The result is that the spokes

a) will never lose their initial tension, thus keeping the wheel perfectly reactive and centred

b) will remain in the position that have been studied in the wind tunnel tests to ensure the best aerodynamic penetration possible.

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.

Wide Rim Tech

Fulcrum®’s R&D 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.

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.

Carbon hubs

In line with their aim to save every possible gram of weight and to choose the most advanced technological solutions, the R&D department has developed a seamless carbon hub.

The fibre selected is woven at 90 degrees, for enhanced balance of torque when pedalling.

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.

Oversize Flange

The Oversize Flange was developed from the need to create a system to transmit every watt to the ground without dispersion, stiffening the wheel system where necessary, without having to add spokes or superstructures that increase weight.

The oversize flange uses physics to solve the problem. It increases dishing and enables spokes to be shortened. Doubling the spokes creates a balanced system that is excellent at transmitting torque.

Monoblock hub for Disc

The rear hub of a top-quality disc brake wheel is a technical problem to be solved. Fulcrum®’s R&D department found itself facing a fundamental choice: on which side to put the oversize flange of the Two-to-one™ system? Disc or sprocket side? Without question - must stay on the sprocket side.

To combat the loss of braking power from flex and torque of the connector between the two sides of the hub, a special one-piece system has been devised with internal stiffening ribs.
