Fulcrum Rapid Red Carbon Wheelset

Specifically designed for gravel riding, this versatile wheelset is perfect for spending the weekend exploring backroads and countryside adventures. It features a high-quality full-carbon rim construction, which makes each wheel durable and stiff, while also keeping the weight impressively low. Fulcrum has also given each wheel a unidirectional (UD) carbon fibre finish, making it look as awesome as it performs. Coming complete with an aerodynamic profile and a range of technologies including Tubeless Ready and 2-Way Fit, this model is a great choice of upgrade for conquering every mile on your gravel bike.

Carbon Fibre Gravel Bike Wheelset

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 know-how from their 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.

2-Way Fit Ready

To achieve maximum performance with tubeless tyres, the Rapid Red Carbon features 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 30mm 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 25mm.

And as you’ve come to expect from #fulcrumfast, Fulcrum has also employed functional solutions that marry aesthetics and performance. At a glance, you will immediately notice the new Direct Inmold Matt Finish (DIMF). The Fulcrum Rapid Red Carbon is the perfect solution for demanding riders looking for a top-of-range product with “made in Europe” technology.

 

Technologies:

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. The brand has developed its 2-Way Fit technology to ensure the perfect compatibility of its 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 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.

Rim Dynamic Balance (RDM): 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: A magnet and lots of ingenuity. This was what led to the patent for the well-tested “Mounting Magnet” system, or MoMag.

Fulcrum Identification Card (FIC) – 100% Handmade Quality: Right from its inception Fulcrum has been marked by the feature that continues to this day: that 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.

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.

Full Carbon Rim 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 its range. To build them Fulcrum 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, and the possibility of giving the spokes more tension and more stiffness which, in terms of performance, means improved responsiveness and acceleration.

Cup and 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.
