By respecting the fundamental points of the Racing Zero family, and interpreting the world of disc brakes, the Fulcrum R&D division has successfully risen to a decidedly complex challenge: that evolving while respecting history to make an absolutely mind-blowing product.
It all starts with the base concept: carbon and aluminum together to create a unique combination, introduced on her sister for traditional brakes, to enhance reactivity and stiffness to the total advantage of a precise, decisive ride.
The 30 mm rim profile helps with lightness uphill, while the wide 19 mm well creates the ideal contact surface for shifting limits to unseen levels. Innovative technologies, such as the new ARC covering that creates an elastic reinforcement on the spoke eyelet, help in this direction.  Unparalleled performance, technology, and innovation. Racing Zero Carbon DB comes into its own on every double-figure uphill gradient, when power transmission is a must. It also delivers downhill, because the wide rim and aluminum spoke support help to make you feel you can dare that extra meter. Racing Zero Carbon DB adapts with style and character to the most diverse of contexts, establishing itself as the absolute benchmark for multi-purpose wheels.


Technologies

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.

Disc specific rim
Fulcrum® is one of the first wheel manufacturers on the market to offer two completely different rim profiles from disc to conventional brake. So, no adaptation, but a rim conceived based on years of design experience. Not requiring a braking track, Fulcrum®’s R&D department designed a completely new profile, aimed at saving every single gram of weight and at improving aerodynamic efficiency. Its greater width makes it a perfect fit for tyres of 25/28 mm upwards.

ARC Technology
Material only where needed, not where it is superfluous. Orienting the carbon fibers with the desired result in mind, thinking of the rim and the sort of wheel we are creating. This is the concept that inspired the Fulcrum R&D division in their development of ARC, the new technology used for layering the sheets of carbon in the mold to create different zones depending on vibration during racing. During study of the rim, the stress points and directions of the forces when accelerating and braking are analyzed to help decide which carbon to use and how to layer it in the finished project. The critical zones, where reinforcement is needed, are usually the spoke eyelets, while the rest of the rim is lightened as much as possible. The difference in material between these two zones can be as much as 20%, acting as reinforcement trussing for the pillars of a bridge.
When requirements are different why use the same structure? Better to choose the most suitable in terms of lightness or fiber direction.
For rim construction, we have chosen T800 high modulus carbon, which guarantees the best weight/performance ratio, as well as enabling complex processing directly in the mold without the need for further stages. Its outside-the-box look therefore derives from a technical requirement, enhancing the character of the wheel and above all further raising the level of the wheel’s response modulation during racing: every cm² is called on to do its job in creating the best combination.

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 we propose to do. We have developed our 2-Way Fit™ technology to ensure the perfect compatibility of our 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: our 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 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. Comparative tests have shown that USB™ bearings are 50% smoother than standard bearings. Now improving your performance during the race or simply going for a ride with your friends will be easier.

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. 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.

DRSC™ - Directionated 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.

Anti-Rotation System™
This new system raises the concept of spoking to new heights of performance.
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, and
b) will remain in the position that was found in wind tunnel tests to ensure the best aerodynamic penetration possible.

MoMag™
Mounting Magnet
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 a wheel without holes on the upper bridge, but with spokes tensioned by traditional nipples!Advantages: No holes on the rim means that the rim is uniform at every point, free from stress points or zones of weakness and, for the clincher profiles no rim tape is required, to the benefit of weight reduction. The advantages are immediately clear: greater rim lifetime, greater resistance to fatigue, the possibility to give the spokes greater tension, and greater stiffness which, in terms of performance, mean greater reactivity and acceleration. But that’s not all. The advantages also include extremely quick and simple maintenance and spoke replacement. All to the benefit of cyclists who choose Fulcrum®.

Unrilled Rim Bed
No holes on the bridge connector means that the rim is uniform at every point, free from critical areas subject to stress.
The advantages are immediately clear: less weight, longer lasting rims, greater resistance to fatigue, the possibility of giving the spokes more tension and more stiffness which, in terms of performance, means improved responsiveness and acceleration.

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.
