Racing Zero - the new Fulcrum racing wheelset designed to underline and further improve your performance on the road

Creating it was less easy, given the premises and the myth it referred to. Fulcrum believe they have succeeded, developing a design along the same lines as that of conventional brakes. The riding experience is the same, exactly similar and equally exhilarating, until you come to the extreme rush at a hairpin bend.

The rims
New aluminum rim with a wider section: ETRTO 19C, external width 23,8 mm. The special milling makes it possible to reduce the peripheral weight of these road bike rims and to increase the reactivity of the wheels.

Hubs and flange
Racing Zero DB’s new disc brake hubs are the result of years of experience in wheel design. Fulcrum team has used oversize flanges to balance braking and accelerating forces, and Two-to-One™ double spokes to guarantee solidity and reactivity when racing.

Spokes and nipples

  • Aluminum spokes: a precise choice to ensure optimal rigidity and a special attention to aerodynamics.
  • Aluminum nipples: thanks to the light weight they reduce the peripheral mass, enemy of reactivity.

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 industrialize all the wheels characterized 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.

Traceability
A guarantee of quality. The keyword for the Fulcrum 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.

Technologies

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.

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.

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 unmovable whole. The result is that the spokes

  • will never lose their initial tension, thus keeping the wheel perfectly reactive and centered
  • will remain in the position that have been studied in the wind tunnel tests to ensure the best aerodynamic penetration possible.

One hub fits all
This solution responds to the need to fit the various axis standard on the market, with speed and ease. Different adapters mean that the wheel is ready to mount on your bike in just a few steps.

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 25/28 mm tyres, the sizes currently popular. This ensures stability, excellent handling and superior comfort.

High strength aluminum
Special aluminum - the best aluminum wheels require carefully chosen materials. For "High strength Aluminum", Fulcrum® R&D uses only the best aluminum alloy 6082, with artificial ageing T6 temper that stabilizes the alloy and gives it maximum life and reliability.
Aluminium 6082 has the highest strength of the 6000 series and has replaced 6061 in many applications. It is generally used for high-stress applications.

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.

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.

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.

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 Fulcrum propose to do. They've developed the 2-Way Fit™ technology to ensure the perfect compatibility of their tubeless rims with normal clincher types and tubes. 2-Way Fit™ 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. The advantages are indisputable: the numerous tests have highlighted an unique increase in smoothness. Because there is no tube, the friction caused by rubbing against the tyre is eliminated, while the perfect adherence of the tyre to the rim prevents the dispersion of energy. Tubeless tyres do not suffer from sudden deflation when punctured which is a great advantage in safety terms. There is also no risk of snake bites as there is no tube to rupture.

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 Fulcrums' R&D department and they've 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.

Square milling
For the new Racing Zero’s aluminium rim, Fulcrum decided to keep the triple-milled structure throughout the profile to minimise aluminium thicknesses. Next, their technicians added 3D milling at the base of the spokes.
This means less material but the same reliability since, in this particular design, the forces are well distributed over the rim.
Triple and “Square” milling enable maximum weight reduction on the rim periphery, producing an extremely responsive wheel.

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.
