Fulcrum Racing 4 DB Wheelset

More Information
Brand	Fulcrum
Colour	Black
Wheel Size	700c

Fulcrum is a subsidiary brand of Campagnolo that produces Alloy and Carbon wheels for road and mountain bikes. Initially developed so that Campagnolo could produce wheels compatible with brake and drive systems by Shimano and SRAM, allowing Campagnolo to retain its exclusivity. However Fulcrum still produce Campagnolo-compatible wheels.

Thanks to the 34mm medium profile, the new Racing 4 DB wheels achieve the perfect balance between aerodynamics, riding precision and versatility. They are ideal for climbing without sacrificing stability once the speed increases on the descents. In fact these wheels have been chosen by the Cofidis team for their training setup.

Compared to the 2018 model, the aluminium rim profile of the new version has been CNC machined and lightened, and the inner rim width has been increased to 19 mm (the previous model was 17 mm wide) so that it can easily fit 25 mm tyres. The wheels also feature 2 Way Fit technology for clinchers and tubeless tyres (tubeless tape installed and valves included). Aesthetically the new Racing 4 DB line features striking laser etched graphics that will resist whatever the weather throws at them.

Technology

Anti-Rotation System™

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.

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.

To ensure the best performance and reliability of its products, each project, before going in the production stage, must submitted to a series of severe tests that validate what has been conceived and designed up to that moment (fatigue test, crash test, tyre burst test, enviroment test, 100% manually assembled and electronically checked).

This is why, from its 2012 range, Fulcrum® wanted to supply each wheel with its own Identity Card (F.I.C.) which uniquely identifies the wheel and certifies that it has been manually assembled and has passed all tests required by the strict quality protocol.

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.

The availability of the International Standard option ensures full compatibility of Fulcrum® wheels even with the most widespread braking systems that use this assembly plan.

Square Milling

For the new Racing Zero’s aluminium rim, we decided to keep the triple-milled structure throughout the profile to minimise aluminium thicknesses. Next, our technicians added 3D milling at the base of the spokes.

This means less material but the same reliability since, in this particular design, the forces are well distributed over the rim. Triple and “Square” milling enable maximum weight reduction on the rim periphery, producing an extremely responsive wheel.
