Fulcrum Rapid Red Carbon: discover new horizons fast

The Rapid Red family of wheels now boasts a set of wheels dedicated to those who want to discover new terrains and new trails, with a touch of extra speed. Fulcrum has applied the technological knowhow from our top of the range wheels to develop the reactive, light and reliable Fulcrum Rapid Red Carbon, for gravel (and for whatever gravel means to you). Lightness and reactivity are guaranteed by the S-Shape asymmetrical profile carbon rim. This technology improves the balance between the tension of the spokes. The optimised balance ensures long term performance levels. Moreover the unique shape of the rim profile increases stiffness by 2.5% compared to a traditional U-shaped profile. To achieve the maximum performance with tubeless tyres, the Rapid Red Carbon feature a tubeless-specific non-drilled bridge: 2-Way Fit. The non-drilled bridge has a C-Lux Finish, a mirror-like finish that makes it easier to install the tyre. The wheel assembly is completed with Fulcrum's patented Mo-Mag technology, which uses a simple and ingenious solution to seat the nipple on the rim hole with a magnet. The rim has a 30 mm high profile with a mini-hook system that extends its compatibility with a wider range of pressures (the only limit is the one given by the tyre). Moreover Fulcrum’s dimensional precision guarantees greater safety against the tyre rolling off the rim at low pressures, thanks to the larger support surface available with the wider inner rim width of 25 mm. The Fulcrum Rapid Red Carbon are the perfect solution for demanding riders looking for a top of range product with “made in Europe” technology.

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. Fulcrum has 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 caused by non-ideal positioning when fitting.

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.

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®.

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 industrialize all the wheels characterized 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 Fulcrum's 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.

AFS Axle System™
The Axial Fixing System™ is the solution developed by Fulcrum® for fixing the disc brake to the hub. The constraint conferred by the fixing rebate surface, which is greater than in already known standards, makes it possible to achieve greater structural rigidity and therefore more precise and powerful braking.

Rim Full Carbon Technology
For the construction of Fulcrum® full carbon rims, laboratory-studied combinations of different types of fibre are used, including unidirectional and the famous 90-degree 3K that finishes the models at the top of our range. For their construction, a special HTG ('high transition grade') resin was developed that has a glass transition threshold at higher temperatures than any other fibre used in the cycle industry. This enables incomparable braking performance.

Undrilled Rim Bed
The absence of holes in the upper deck is synonymous with a product that is homogeneous throughout, free of critical points subject to stress. The advantages are immediately perceived: less weight, longer rim life, greater resistance to fatigue, the possibility to tension the spokes more and greater stiffness which, in terms of performance, mean more reactivity and acceleration.

Cup & Cone
The CUP & CONE bearing differs from classic cartridge bearings in that it works perfectly on axis with the forces in play, weight and thrust coming from the frame, since the balls run on a raceway positioned in direct opposition to these forces.
