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 2-Way Fit™ technology to ensure the perfect compatibility of 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 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.

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™
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.

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.

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.

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.

Square Milling
For the new Racing Zero’s aluminium rim, we decided to keep the triple-milled structure throughout the profile to minimise aluminium 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.

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.
