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. We have 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.

TECHNOLOGY

2-WAY FIT (ROAD): 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 Fitroad 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. For top 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.

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.

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.

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.

CUP & CONE: 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. The adjusting ring lets you pre-load the bearing, so you can eliminate side-to-side play and have optimum adjustment once the wheel is mounted on the frame.

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.
