Thanks to the 34 mm medium profile, the 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 set-up. Unlike the 2018 model, the aluminium profile of this new version is CNC-machined, making it lighter, and the internal dimension has been increased to 19 mm (the previous model had 17 mm internal dimension) so that 25mm tyres can now be mounted without any problems. The wheels also offer 2-Way Fit technology for clincher tyres and tubeless tyres (tubeless tape is factory-fitted and valves are included). To match the look of the new Racing 4 DB, there are impressive laser-etched graphics that can withstand any weather.
