Racing Zero switches to carbon for the first time, and does it in its own way: they are the first road bike wheels on the market that combines a carbon rim with aluminum spokes.
This new hybrid technology combines the legendary rigidity of the aluminum Zero with improved reactivity, thanks to the carbon bike rims, which reduce the peripheral weight and so the moment of inertia.
A light wheel, with a superior handling and an optimal power transmission to the ground.
30 mm high carbon bike rims with a wider cross section: this wider base provides more grip, more comfort and a superior handling.
The rims are made from UD - unidirectional carbon, among the best-performing currently available on the market.
The use of 3K fiber on the braking surface provides better braking feedback.
Racing Zero Carbon setup provides aluminum aero spokes: this choice was made to ensure optimal rigidity whilst paying special attention to aerodynamics.
The legendary Racing Zero’s steering precision starts here.
Racing Zero Carbon are the first road bike wheels on the market with carbon rims and aluminum spokes: this means that the nipples, the connection between the two different materials, had to be studied and redesigned.
The new nipples, inserted thanks to MoMag technology, are specially shaped to facilitate the assembly process and to stay in place without the addition of any other cushioning material.
Hubs And Oversize Flange
The front hub has been redesigned, the new model is smaller and so lighter.
Smoothness is ensured by the famous USB ceramic bearings.
Carbon hub with 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 the wheel.
The concept is simple and elegant: balance the weight of the gasket, with an item of similar weight placed on the exact opposite side.
USB - Ceramic Ultra Smooth Bearings
Fulcrum has a long-standing reputation for the extremely high performance of its hubs in terms of smoothness and reliability.
In fact, all the projects are entirely developed in their R & D department and they have put obsessive care into taking care of every detail.
The hubs with USB ceramic bearings (Ultra Smooth Bearings) further enhance the triathlon and road bike wheels’ smoothness and reduce weight and the need for maintenance.
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.
This new system raises the concept of spoking to a new level of performance for road bike and triathlon wheels.
The Fulcrum engineers have redesigned the spokes and the hub housings to create a solid and unmoveable whole. The result is that the spokes
It will never lose their initial tension, thus keeping the wheel perfectly reactive and centred.
It will remain in the position that have been studied in the wind tunnel tests to ensure the best aerodynamic penetration possible.
3Diamant: Surface Treatment for Braking Tracks
Mediocrity is not synonymous of quality standard, Fulcrum is continuously researching all new standards of performance for its products. Even if the current brake performances on the full carbon wheelsets, were already of a high quality, Fulcrum engineers wanted to improve even further the power of the brake and shorten the braking distance of its products.
