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.
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.
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.
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.
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.
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.
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.
The Oversize Flange was developed from the need to create a system to transmit every watt to the ground without dispersion, stiffening the wheel system where necessary, without having to add spokes or superstructures that increase weight.
The oversize flange uses physics to solve the problem. It increases dishing and enables spokes to be shortened. Doubling the spokes creates a balanced system that is excellent at transmitting torque.
AC3™ - ALL CONDITIONS CARBON CONTROL
AC3™ - ALL CONDITIONS CARBON CONTROL
For years, the issue of braking on carbon rims has been studied and technically updated, in accordance with progress made in research into materials and available finishing processes.
AC3™ is a further step forward in this direction and it will enable surprising braking performance, especially in difficult conditions, when improvements become the base for a different way of cycling.
The Fulcrum R&D division has chosen to change its approach to braking track production, going from a mechanical process to one that uses micro laser incisions on the surface to eliminate resins and perfect roughness.
In this way, braking directly exploits the brake pad’s contact on the fiber, improving grip and dissipation of water and moisture from the surface, allowing it to work immediately in ideal conditions and give better results.
Confidence and power grow, together with excellent modularity. Lab tests have shown that this greater force enables a 6% improvement in braking power in dry conditions compared to previously. In the wet, the difference is amazing: here there is a 43% increase, bringing braking distance close to those in dry conditions.
The cyclist can concentrate totally on choosing the best line, with no slip-ups, each hairpin a work of art.
