From the manufacturer's official website:

Racing Zero wheels are made to be stars - the revolutionary anodized red colour immediately confirms it. Impossible not to note them in the group. RacingZero wheels stand out but do so with style.

RacingZero wheels are positioned at the top of the Fulcrum® aluminium range. The rims with a height of 26 mm are made by a special extrusion process which considerably thins the walls, giving a notable reduction of the overall weight, but without compromising strength. Further lightening has been carried out between the spoke anchoring points ? where there are no stresses ? thanks to the exclusive Fulcrum® triple milling system. The rim bed has no holes, and this translates into higher torsional rigidity and vertical elasticity for the wheel.

The spokes ? 16 on the front wheel and 21 on the rear ? are in aluminium with a variable-section aerodynamic profile and tensioned by special Ergal nipples. Rear spoking are laced by doubling the spokes on the drive side, in accordance with the Fulcrum® 2:1 Two-to-One™ spoking system This allows a more effective transmission of the drive torque and a more appropriate distribution of the wheel stresses.

The front wheel spoking, on the other hand, is radial to obtain better aerodynamics.
Hubs are oversized with aluminium body and axle and with adjustable high-precision bearings.
Like the entire Fulcrum® range, RacingZero wheels incorporate the patented Dynamic Balance™: the wheel's rotation dynamics are balanced thanks to the astute distribution of the peripheral masses which counters the joint section with a special rim design.

RacingZero wheels are available in clincher and tubular tyre versions and are compatible with both Campagnolo®, Shimano® and Sram® drivetrains.

2:1 Two-to-One™ Spoke Ratio
When you push on the pedals, the rotational force on the sprocket induces a slackening of the freewheel spokes with a consequent loss of rim tension. This results in undesirable flex of the whole wheel and an unavoidable loss of energy. Fulcrum® has solved this classic cycling problem with its 2:1 Two-to-One™ Spoke Ratio patent, by doubling the spokes in the critical zones.

As a result there are two spokes which carry out the function of one, slackening and torsion are limited and the transfer of the athlete’s power is much more effective. Also, thanks to this system, spoke tensions are balanced more evenly between drive and non-drive sides and the fatigue life of the rim, hub and spokes is lengthened.

Dynamic Balance™
Unlike carbon rims, all the aluminium rims are joined. The joint, though indispensable, entails a concentration of material in a single point and creates an annoying “jump” effect at speed. Fulcrum® has eliminated this annoying problem with the Dynamic Balance™ patent.
The concept is simple and elegant: balance the mass of the joint with a mass of the same weight. For top models, this is obtained by a special operation on the section of the rim opposite the rim joint. For entry-level models, Dynamic Balance™ is obtained by using two oversized spokes in the section opposite the joint. The result is a wheel with perfectly balanced rotational dynamics.

MoMag™
Though they have no holes in the rim bed, Racing3, Racing1 and RacingZero rims have spokes tensioned by traditional nipples. This makes tensioning and changing the spokes extraordinarily easy, and does away with questionable anchoring systems on the rim.
This solution was made possible thanks to the Fulcrum® MoMag™ patent which exploits magnetic power and a good dose of ingenuity to guide the nipples to the correct rim holes.
