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 victory!

Technologies

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.

DRSC - Directionared 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 - 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.

Fulcrum Identification Card (FIC) 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.

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 4mm 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.

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.

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.

Features

Rim This special triple milling makes it possible to reduce the peripheral weight of these road bike rims and to increase the reactivity of the wheels. 

Differentiated rim height: 27mm at the front to have a good handling; 30mm at the rear to transfer all the power to the wheel.

HubsThe front hub has been redesigned, the new model is smaller and so lighter. 

Smoothness is ensured by the famous USB ceramic bearings. The cap and cone technology maintains the most efficient angle of contact between the bearings and bearing seat, increasing the smoothness and durability. 

The front carbon hub and oversize aluminum rear flange provide an innovative mix that provides excellent torsional rigidity and consequently a greater reactivity. 

Greater reactivity to each change in pedaling time and more efficient power transmission to the wheel.

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.
