Fulcrum Racing Zero Carbon C17 Road Wheelset 28" 9×100/10x130mm CA 9-12-speed Clincher Black

Its first appearance represented a groundbreaking innovation in the field of low-profile wheels.
The innovation of the Racing Zero Carbon lies in its concept. Carbon and aluminium together to create a unique combination, creating a reinterpretation of the Racing Zero myth that is at the forefront of the range. There have always been accompanying comments such as “super stiff thanks to the aluminium spokes, super responsive thanks to the light rim”, you steer “as precisely as a razor blade” or “solid and comfortable, light and stable in the hectic moments of the race”.

What more is there to add? Nothing, except to improve this racing wheel with a new, even lighter, even more responsive and even stiffer rim.
The goal of Fulcrum’s R&D department was clear and perhaps banal: not to touch the character, but to improve the performance.
The basic dimensions of the new rim remain the same: 30 mm high, 17C channel that fits well with 25 mm clincher tyres. However, the material and the internal and external structure change. “Twill” carbon is used, while braking is improved with the new AC3 technology.

Racing Zero Carbon is a Racing Zero that runs faster, the most refined and innovative. It is the road bike wheel for the advanced marathon cyclist, the passionate rider who covers his kilometres in search of good times on the climbs, the right feeling and sporting satisfaction. For all those in search of the myth in its highest form of expression.

RDB RIM DYNAMIC BALANCE
The concept is simple and ingenious: balance the mass of the rim joint with an equal-value mass positioned exactly opposite.

USB – CERAMIC ULTRA SMOOTH BEARINGS
Fulcrum has always been respected for the extreme smoothness and reliability of its hubs. These characteristics are due to the fact that all projects are developed in the R&D department and an almost manic attention is paid to every detail. The hubs with USB (Ultra Smooth Bearings) ceramic bearings further increase the smoothness of the wheels and reduce weight and maintenance.

2:1 TWO-TO-ONE
At the moment the rider pedals at full power, the rotation of the sprocket set causes the spokes on the freewheel to give way, resulting in a loss of tension in the rim. This causes excessive bending of the whole and this inevitably means a loss of energy. Fulcrum has solved this classic problem in cycling with its patent 2:1 Two-to-One Spoke Ratio, that is, by doubling the number of spokes in the critical areas.

MOMAG
What is MoMag? A magnet and a lot of expertise. This is how the patent of the tested “Mounting Magnet” system, i.e. MoMag, was born.

ANTI-ROTATION SYSTEM
This new system takes the concept of the lacing system to a new level of performance. Fulcrum’s technicians have redesigned the spokes and the hub shells to create a solid and solid unit. In this way, the spokes
a) they never lose their initial tension, keeping the wheel perfectly responsive and centred, and
b) that they remain in the position developed in the wind tunnel to ensure the best possible aerodynamics.
