Every project detail has been developed to combine accuracy, consistency and reliability. This is a better way to live your passion, to head straight to the podium and to make every ride a day to remember.
Triple milled aluminium with momag construction:
Unique form provides more lateral stiffness. Weight reduction removes rotational weight translating into increased performance.
Oversized nipples in aluminium:
Reduce the peripheral mass of the wheel while increasing structural integrity
Spokes: double butted stainless steel with reinforced head
Less weight, improved reactivity and stiffness, increased structural integrity
Hub body: carbon construction:
Provides a high level of lateral stiffness and reduces the weight.
Sealed industrial bearings
Exceptional quality and smoothness; high efficiency over time.
Free wheel titanium body:
Reduces the weight of the wheel while increasing structural integrity. Titanium design doesn’t scar as is often the case with aluminum hubs.
Oversize axle: aluminum construction
20mm axle makes for sturdier construction while aluminum structure reduces the overall weight of the wheel.
2:1 Two-to-One Spoke Ratio
What is Two-to-One:
A system that is as simple as it is effective, the result of the ingenuity of the 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 wheel, 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 making room for the sprocket set, has to compensate for the traction of the force on the chain side.
So how can we keep the wheel perfectly in balance even when it is stressed by braking and acceleration? By doubling the number of spokes and positioning them in such a way that, for each stress on one side of the wheel, there is an equal and opposite force on the other side. This may seem like a simple solution, but especially on harsh and demanding terrains like those of off-road riding, the 2:1 Two-to-One system is crucial for ensuring consistent control of your bike even in the most critical situations.
Advantages: The advantages are truly striking.
In braking, the front wheel maintains the desired trajectory and does not skid, while the rear wheel, precisely due to this spoking system, reaches a high level of torsional stiffness that enables the optimal transfer of power to the wheel. The 2:1 Two-to-OneTM system also makes it possible to reduce the unit load sustained by each spoke, and this minimises mechanical stress, prolonging the life of the wheel.
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. The availability of the International Standard option ensures full compatibility of Fulcrum wheels even with
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
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 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.
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.
To ensure the top performance and reliability of its products, each project, for the production stage, must undergo a series of very strict tests that validate what has been conceived and designed up to that moment (fatigue test, crash test, tyre burst test, enviroment test, 100% manually assembled and electronically checked).
This is why, from its 2012 range, Fulcrum wanted to supply each wheel with its own Identity Card (ID) which uniquely identifies the wheel and certifies that it has been manually assembled and has passed all tests required by the strict quality protocol.
A guarantee of quality:
The keyword for our products is: traceability.
If you find a little label affixed to Fulcrum products, don’t remove it. This is because it is there to provide you with a guarantee that in the event of the ascertained defectiveness of a production batch your component or wheel will be traceable.
All this because, faithful to its mission, Fulcrum demands absolute perfection and safety for its customers.
What is the ideal wheel?
This is the question that every rider asks before buying a wheel – and Fulcrum wants to help you find an answer! This is why, in collaboration with professional riders and cycling enthusiasts, we have defined the 3 most important parameters that will enable you to choose the best wheel for your riding style and needs.
What does W.R.S. mean
There is little need to describe it. The weight of the wheel is the first question that all riders ask themselves when they buy a wheel. The weight parameter is extremely important, more than any other bike component. Indeed the wheel is a rotating mass and as such it follows the laws of physics that determine its acceleration and inertia. Fulcrum has always designed its wheels with this aim in mind and, at the same time, combining and adapting it to wheel performance in terms of the stiffness, reactivity and reliability.
How “ready” and fast does the wheel feel every time you change gear? The level of reactivity refers precisely to this concept. Reactivity depends on the weight of the rim and of the wheel as a whole, on torsional rigidity (i.e. how much the wheel flexes around the hub when the rider pushes on the pedals), on flexional rigidity (i.e. how much the wheel maintains its shape if, because of pedalling, it moves away from its vertical axis) and on inertia.
This will help you understand and compare various wheels degree of smoothness, thanks to, the use of highperformance CULT ball bearings or USB ball bearings or to other technological solutions applied on the wheel, such as 2-Way Fit .
