Fulcrum Racing 4 DB C19 Road Wheelset 28" 12x100/12x142mm XDR 11/12-speed Disc CL Clincher TLR black

Thanks to the 34mm medium profile, Racing 4 DB wheels achieve the perfect balance of aerodynamics, precision and versatility. They are ideal for long climbs without losing stability on fast descents. That's why Team Cofidis chose these wheels for their training setup.

Unlike the model, the aluminum profile of this new version is CNC machined, making it lighter, and the internal dimension has been increased to 19mm (the previous model had 17mm internal dimension) to now easily fit tires. The wheels also offer the 2-Way Fit technology for clincher tires and tubeless tires (tubeless tape is mounted from the factory and valves are included). For the appropriate look of the new Racing 4 DB provide impressive laser-etched graphics that can withstand any weather.

ANTI-ROTATION SYSTEM
This new system takes the concept of the single-feed system to a new level of performance. Fulcrum engineers have redesigned the spokes and hub shells to create a strong and solid unit. In this way applies to the spokes:
a) they never lose their initial tension, keeping the wheel perfectly responsive and centered, and
b) that they remain in the position developed in the wind tunnel to ensure the best possible aerodynamics.

F.I.C. FULCRUM IDENTIFICATION CARD - 100% HANDMADE QUALITY
Fulcrum, is characterized by an approach since its inception that continues to this day: Design, prototype development and industrialization of all wheels with the red "F". Each wheel component, the selected materials and the technologies used are the tangible result of the efforts that the company Fulcrum spends every day to offer you the highest performance and reliability.

AFS AXIS SYSTEM
The Axial Fixing System is the solution developed by Fulcrum for fixing the disc brake to the hub. The constraint granted by the impact area of the release mechanism, which is greater than that of the known standard mechanisms, allows greater structural rigidity and therefore more precise and efficient braking.

SQUARE MILLING
For the aluminum rim of the new Racing Zero, they decided to leave the triple post-milling structure on the entire profile to minimize the thickness of the aluminum. Finally, the engineers have added 3D-Fr milling finishing at the base of the spokes: This means less material and the same reliability, because with this special design the forces on the rim are well distributed. Triple milling finishing and "Square Milling" allow the greatest reduction of the rim circumferential weight to make the wheel extremely acceleration friendly.
