The gold standard among high-level aluminum road bike wheels.

With the unmistakable character that everybody knows well, the absolute ability to transmit your energy on the asphalt, its extreme riding precision.
Unrivaled in the peloton: extraordinary performance and high impact aesthetics make these road bike wheel the point of reference for cyclists.
Race after race, Zero wheels have become synonymous with excellence, quality, performance, reliability… and now tubeless too!

Technologies

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 Fulcrum propose to do. 

They have developed their 2-Way Fit technology to ensure the perfect compatibility of Fulcrum 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.

Rim Dynamic Balance (RDB) - For those who always want the next best thing, in range and performance, moving up the Gran Fondo rankings. Fulcrum might say it is the fastest ever aluminium 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 centimetre. “Competizione”, for the truly competitive.

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.

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.

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.

Tracebility - A guarantee of quality. The keyword for Fulcrums 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.

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.

Specific Nipple Housing - Such a small part, yet so important. The nipples and their housing are one of the most important element that are taken into account during the design of a wheel.

During the development of the new E-Mtb Fulcrum rims, a lot of work was put into this aspect. The housing has been re-designed and now it makes it possible to eliminate completely the nipples' hard work.

Thanks to a special housing, with side guides on both sides, the nipple sets on a stable base, perfectly in position, oriented towards the spoke.

This makes it possible to make the distribution of the tensions in the rim more even, creating thus perceptible benefits in terms of effort and rigidity: this prevents misalignments under stress and, as a consequence, deformation to the structure.
