Ready for long days on the road, this wheelset is equipped with a hard-wearing aluminum rim construction, which offers an excellent combination of strength, durability and performance as you clock up the miles. Fulcrum has also kitted out this model with an asymmetric rim design that’s engineered to improve rim tension, balancing the forces from your disc brakes and sprocket cassette. Another highlight is its 24 rounded straight-pull stainless steel spokes, which ensure smooth and stable rolling performance as you go the extra distance. Coming complete with sealed cartridge bearings and many of the brand’s finest technologies including 2-Way Fit, this is a great choice of upgrade for low rolling resistance, increased grip and greater protection thanks to its tubeless compatible design.
Endurance Road Bike Wheelset
The Racing 5 DB wheels are the perfect choice for endurance bikes. The lower aerodynamic resistance and decreased stiffness, achieved with the lower 24mm U-shaped profile, makes them the ideal technical choice for long rides without having to worry about climbing, rain or wind, with a consequent saving in energy and increased comfort.
2 Way Fit Ready Technology
In this case to the aluminum rim has seen an increase in the inner channel width, up to 20mm from the previous model’s 17mm, and the addition of the innovative 2 Way Fit system, to comfortably fit 25-28 mm tires, both clinchers and tubeless (tubeless tape installed and valves included).
The esthetics have undergone the same intervention as the Racing 4 DB model, with the updated laser-etched graphics, ensuring the long life of their striking design.
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 unmovable whole. The result is that the spokes will never lose their initial tension, thus keeping the wheel perfectly reactive and centered. The spokes will remain in the position that has been studied in the wind tunnel tests to ensure the best aerodynamic penetration possible.
**Fulcrum Identification Card (F.I.C.) 100% Handmade Quality:**Right from its inception Fulcrum has been marked by a 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.
**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.
Asymmetric Rim: The asymmetry is designed to improve rim tension, balancing the forces from brakes and sprocket cassette.
**2-Way Fit Ready:**This procedure transforms Racing 5 DB wheels (designed to be used with a clincher tire and inner tube) into tubeless ready wheels (i.e. with a Tubeless Easy tire, no inner tube and compulsory use of a sealant liquid). Use of tubeless and tubeless ready tires is forbidden on 2-way Fit Ready rims without official Fulcrum 2-way Fit Ready adhesive tape. This model comes with tubeless type installed and valves included.
