Wheel(s) DUKE BACCARA ULTRA 36 SLR2 / DUKE BADBOY CL

BACCARA 36C SLS2 ULTRA DISC RIM
carbon DUKE Rim UD, developed and tested in Vendée (France).
New DUKE carbon UD rim, designed, developed and tested internally. For its wheels, DUKE owns the manufacturing tools!

The new DUKE Baccara SLS2* wheels are the latest evolution of the essential 3K Baccara. They are now available in 36mm, disc braking, symmetrical or asymmetrical profile. For this new generation, we worked on 3 points: weight, comfort and aerodynamics. Thanks to the SLS2 technology we have lowered the weight by 10%, due to the use of high modulus fibers and a new process of molding in sealed enclosure with resins of new generation. This process also allows better filtration of vibrations generated by the particle size of the bitumen. The comfort is improved. The inside width between hooks is larger with 21mm. This gives more volume to the tires and thus improves performance, comfort and cornering grip. A wide rim also means being able to use thinner and lighter tires while maintaining the comfort, softness and grip provided by a larger volume of air. The recommended tire widths are 25mm and 28mm, tubeless or tubetype. The profile of the rim has been reworked to improve its aerodynamics and stability in all wind conditions. The outer width is larger with 27.6 mm and has a new warhead shape. This reduces aerodynamic drag and thus increases its speed. The wheels are also less sensitive to side wind and the steering more precise, the cyclist feels more confident. The best results are achieved with 25mm tires. It also retains a version with asymmetric profile of 2mm. With the increase in the number of speeds, the cassette side flange of the hub is seen more and more recentered towards the inside of the wheel. The umbrella spokes opens further and this reduces the stability and lateral stiffness of the wheel: it is fuzzy in the raises, takes sail easily. Asymmetry gives an umbrella much higher than the symmetrical rims and rebalances the tensions of the two plies for more rigidity and durability.
