Fulcrum Racing Zero Carbon Disc Brake 2-Way Fit Clincher Wheels - Options.

ABOUT PRODUT:      

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.

    MAIN FEATURES:

    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 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 cau

    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.

    2:1 TWO-TO-ONE SPOKE RATIO™ - DISC BRAKE


    A system that is as simple as it is effective, the result of the ingenuity of Fulcrum® engineers and attentive observation of the results of the tests performed on the wheels on a daily basis.

    These tests made it possible to understand that the forces that act on the sides of the wheels, and therefore on the spokes, are extremely different; but what’s more, the differences between the front and rear wheels are also evident and significant. The front wheel, in fact, has to remain stable even during braking of the disk on the left side, and the rear wheel, in addition to the sprocket set, has to compensate for the traction of the force on the chain side.

    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.

    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™.

    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.


    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.


    RIM FULL CARBON TECHNOLOGY

    Full carbon Fulcrum® rims are built using combinations, developed in the laboratory, of different types of fibre, including UD and the famous 90-degree 3K of models at the top of our range.
    To build them we developed a special HTG (high transition grade) resin, whose glass transition point is at a higher temperature than any other fibre used in the bicycle industry.
    This gives incomparable performance when braking.


    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.

    UNDRILLED 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.

    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.


    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.

    SPECIFIC NIPPLE HOUSING

    7% more reliable.

    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.

    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.
