Plasma Electrolytic Oxidation Treatment
A completely new technology combines a very engaging total black look with high range specs, including a special braking surface that creates new standards for braking on aluminum road bike wheels.
The Plasma Electrolytic Oxidation process gives the braking surface very special characteristics regarding hardness and wear resistance.
This is possible thanks to a very fine and compact matrix of alpha and microcrystalline gamma alumina and amorphous alumina embedded on the surface. Thanks to the high hardness of the layer, this new wheel presents excellent wear resistance.
Fulcrum R&D department has developed a new design for Racing Zero Nite’s braking surface. The design created by turning allows superior braking efficiency. Specific blue brake pads should be used with this new model.
Triple Milling: this special triple milling makes it possible to reduce the peripheral weight of these road bike rims and to increase the reactivity of the wheels.
Differentiated rim height: 26mm at the front to have a good handling; 30mm at the rear to transfer all the power to the wheel.
Oversize aluminum flange and Two-to-One™ technology: the doubling of the spokes on the cassette side provides greater torsional stiffness and therefore a greater reactivity at each pedal stroke. This means greater efficiency in the transmission of power to these type of road bike wheels.
The front hub has been redesigned, now it is smaller and lighter than before, smoothness will be ensured by the well known USB™ bearing technology.
The cap and cone technology maintains the most efficient angle of contact between the bearings and bearing seat, increasing the smoothness and durability.
Spokes and nipples
Aluminum spokes and aluminum nipples: thanks to the light weight they reduce the peripheral mass, enemy of reactivity.

Racing Zero with Shimano Inc. FW body is compatible with 10 and 11 speed sprockets.
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.
