FULCRUM RACING ZERO COMPETIZIONE C17 HG11 WHEELSET

For those who always want the next best thing.

We might say it isthe fastest ever aluminum Racing Zero– the perfect definition! A breathtakingly smooth run (thanks to CULT™ technology).

This rim is born to take on the bends, without giving a centimeter. “Competizione”, for the truly competitive.

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 tyres 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.

THE ADVANTAGES

The advantages are indisputable: our tests have highlighted a 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 get injured. What if a tubeless tyre gets punctured? There’s nothing to be afraid of… With the Fulcrum® 2-Way Fit™ you can remove the tubeless valve and fit in a standard clincher tire that will let you ride back home.

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 resistant 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.

THE DIFFERENCE

The test performed involves spinning the wheel to 500 rpms then letting it decelerate.
The test results are amazing: the road bike wheels equipped with CULT™ ball bearings continues its motion for a full 45 minutes, i.e. nine times longer than standard bearings.

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.

Aluminum RIMS

For top models, this is obtained by a special operation on the section of the rim opposite the rim joint.
For entry-level models, Dynamic Balance™ is obtained by using two oversized spokes in the section opposite the joint. The result is a wheel with perfectly balanced rotational dynamics.

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.

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!

ANTI-ROTATION SYSTEM™

This new system raises the concept of spoking to a new level of performance for a 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 centered
b) will remain in the position that has 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.

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.

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.

SQUARE MILLING

For the new Racing Zero’s aluminum rim, we decided to keep the triple-milled structure throughout the profile to minimise aluminum thicknesses. Next, our 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.

DIFFERENTIATED RIM HEIGHT

Two different heights for front and back. A bigger challenge in construction, but necessary to achieve the very best.
The lower front wheel improves handling, limiting weight to a maximum and also mass involved when turning and relaunching.
The rear rim is higher and more solid, to transmit all the power to the wheel and increase stability.

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 aging T6 temper that stabilises the alloy and gives it maximum life and reliability.
Aluminum 6082 has the highest strength of the 6000 series and has replaced 6061 in many applications. It is generally used for high-stress applications.

CARBON HUBS

In line with its 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 an enhanced balance of torque when pedaling.

PLASMA FREEHUB

The Plasma treatment makes the aluminum especially hard and resistant to surface abrasion and wear. This has allowed the 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.
