Fulcrum Racing 4 DB 700c Road Wheel - Front

Reliability, versatility and winning looks are the key words of the new Racing DB, Fulcrum’s range of entry-level aluminum wheels for disc brakes equipped road bikes. First launched in 2018, the three new versions of the ever popular, Racing 4, 5 & 6 DB have been redesigned from the ground up. All are now tubeless ready - with 2-Way FitTM Ready. All with wider rim profiles - to better support modern tyre preferences. All with faster freehub engagement for a more direct power transfer and better ride dynamics. The aim is to provide wheels that ensure reliable performance in different conditions, whether it’s finding the right training setup, riding long distances or choosing a second set of wheels to fit to your gravel bike. And as per the #fulcrumfast tradition, the three new models feature a clean and minimalist racing look, that will still turn heads on your ride.

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 aluminum 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 tires. The wheels also feature 2-Way FitTM Ready technology for clinchers and tubeless tires (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.

2-Way Fit
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. They've developed 2-Way Fit™ technology to ensure the perfect compatibility of tubeless rims with normal clincher types and tubes. 2-Way Fit™ 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 tire. Housing the valve for tubeless tires is also risk-free, with the unquestionable advantage that there are never any air infiltrations caused by non-ideal positioning when fitting. The advantages are indisputable: the tests have highlighted an unique increase in smoothness. Because there is no tube, the friction caused by rubbing against the tire is eliminated, while the perfect adherence of the tire to the rim prevents the dispersion of energy.
Tubeless tires do not suffer from sudden deflation when punctured which is a great advantage in safety terms. There is also no risk of snake bites as there is no tube to rupture.

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.

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.

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 absolute perfection and safety for its customers.
