26mm at the front to have a good handling; 30mm at the rear to transfer all the power to the wheel.
This special triple milling makes it possible to reduce the peripheral weight of the rim and to increase the reactivity of the wheel.
Allows to obtain a perfectly even structure and to remove tension areas in the rim.
A precise choice to ensure optimal rigidity and a special attention to aerodynamics.
Thanks the light weight they reduce the peripheral mass, enemy of reactivity.
The front hub has been redesigned, the new model is smaller and so lighter. Smoothness is ensured by the famous USB™ ceramic bearings.
The front carbon hub and oversize aluminum rear flange provide an innovative mix that provides excellent torsional rigidity and consequently a greater reactivity. Greater reactivity to each change in pedalling tempo and more efficient power transmission to the wheel.
The cap and cone technology maintains the most efficient angle of contact between the bearings and bearing seat, increasing the smoothness and durability.
The freehub body for Shimano-SRAM will be submitted to Plasma Electrolytic Oxidation treatment in the laboratory. Despite the thickness of the material being reduced to the minimum, the duration and strength are maintained with the benefit of a lower weight.
The advantages are indisputable: our tests have highlighted an unique increase in smoothness. Because there is no tube, the friction caused by rubbing against the tyre is eliminated, while the perfect adherence of the tyre to the rim prevents the dispersion of energy. There is also no risk of snake bites as there is no tube to rupture. What if a tubeless tyre gets punctured? With Fulcrum 2-Way Fit™ you can remove the tubeless valve and fit in a standard clincher tire that will let you ride back home.
Reduces the overall weight of the wheel
Steel spine and eccentric, lever with drill lightening and aluminum die. Eccentric-closure system allows cyclist to modulate the pressure necessary for heightened sensitivity to find the proper closure for the block. Easy to use, with a material resistant to wear and tear, rust, and pressure
The Racing Zero wheel is entirely hand-assembled by a specialised Fulcrum® technician and is checked in every tiny detail with electronic instrumentation. This ensures maximum performance and reliability for all Fulcrum® wheels.
