When do you get used to counting kilometers in tens of thousands? How many times have you imagined a set of all-purpose wheels, excellent in the winter, agile and performing uphill, with no limits on less-than-perfect road surfaces, reliable and ready when you need to concentrate exclusively on your training, and a loyal companion when your goal is big mountain passes, great distances and big adventures?
Racing 3 DB is a concentrate of technology designed to raise the performance bar in a wide range of situations, setting new standards for satisfaction and reliability.
This wheelset for racing and gravel bikes was not designed to dazzle. The focus here was on substance and the R&D division at Fulcrum have taken everything to a higher level, choosing the most balanced, evolved technical solution for every single essential component… Who says it won't dazzle once on the road? Extremely smooth thanks to cone and cup bearings and comfortable thanks to steel spokes that ensure 25% more shock absorption capacity than its racier Racing Zero counterpart.
The 19 mm wide well also ensures generous, robust, stable contact with the road. "Versatility" for Racing 3 DB means making the difference whatever the context: as a training wheel, for long distances and on gravel. It is also a high class upgrade for those who enjoy cycling without any competitive intent.
Good-looking, refined, detail-attentive construction, with R2-Milling that combine design and hi-tech. Multi-purpose, distinctive, a Fulcrum icon.
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 Fulcrum propose to do.
Fulcrum has developed the 2-Way Fit™ technology to ensure the perfect compatibility of their 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 caused by non-ideal positioning when fitting.
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 aluminium rim 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.
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.
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™.
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 wheels without holes on the upper bridge, but with spokes tensioned by traditional nipples!
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.
This new system raises the concept of spoking to a new level of performance for road bike and triathlon wheels ( and mtb too) 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.
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.
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.
The cup-and-cone bearing differs from the classic cartridge bearing because it works in perfect alignment with the forces involved, weight and thrust from the frame, as the bearings run in a race positioned directly opposing these forces.
Special aluminium - the best aluminium wheels require carefully chosen materials. For "High strength Aluminum", Fulcrum® R&D uses only the best aluminium alloy 6082, with artificial ageing T6 temper that stabilises the alloy and gives it maximum life and reliability.
Aluminium 6082 has the highest strength of the 6000 series and has replaced 6061 in many applications. It is generally used for high-stress applications.
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.
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.
