Fulcrum racing quattro carbon wheelset

The pair of Fulcrum Racing Quattro Carbon H40 clincher wheels with Shimano Campagnolo core and QR axle seek to become the ideal companion for every day, in any situation. A magical balance: the new 40mm profile will shine on any road. The ride is aerodynamic, stable and fast. On climbs it stays light, and is reactive for relaunching. On the descents, firm and tame.

Features:

- Rim: carbon, a combination of UD fiber - unidirectional and 3K on the inside. Height 40mm, oversized section: ETRTO 17C, 24.5mm outer. 3K carbon braking track with 3Diamant treatment to guarantee power and maximum sensitivity in all conditions during braking

- Weight: 1555 g

- Includes brake pads

- Hubs: Aluminum hub system with high quality steel adjustable bearings. Aluminum hubs with oversized aluminum flange and Two-to-One technology at the rear to transmit all the power to the ground

- Spokes and nipples: Variable section steel aerodynamic spokes. Aluminum nipples

- Compatible hub: Shimano, Campagnolo

Technologies:

- Dynamic Balance

The concept is as simple as it is ingenious: Weigh the mass of the rim seal with a mass of similar value positioned exactly opposite. As for carbon wheels, the principle is the same, but the technology is different. For carbon wheels a particular procedure is used in the phase of alignment of the carbon blades so that the wheel is always balanced.

-Two-to-One

Fulcrum is known for the extremely high fluidity and reliability performance of its bushings. This is so because all designs are developed in-house in the R&D department, and every detail is obsessively cared for.

The hubs are equipped with USB (Ultra Smooth Bearings) ceramic bearings that further increase the level of fluidity of the wheels and reduce weight and maintenance. Comparative tests have shown that USB bearings are 50% more fluid than standard bearings. Increasing the performance of your bike in competition or just pedaling with your friends will now be easier.

- MoMag or Mounting Magnet

What is the MoMag? A magnet and a lot of ingenuity. Thus was born the patent for the proven "Mounting Magnete" system, or MoMag.

How does it work? Once the spoke nipples have been inserted into the rim through the valve hole, they are "guided" to the point of engagement with the spoke by the magnet.

This great and simple measure allows to obtain a free wheel of holes in the upper bridge, but with a tensioned spoke by means of the nipples of the traditional spokes. Advantages: a rim without holes means a rim that is homogeneous in all its points, free from critical points or breakage areas and, the tire profiles do not require the rim tape, which offers important advantages in terms of weight. The benefits can be seen instantly: longer rim life, greater resistance to fatigue, the possibility of tightening the spokes even more and more rigidity which, in terms of performance, means greater reactivity and acceleration. And not only that. Another benefit is the maintenance or replacement of the spokes, which is thus extremely easy and fast. These are all advantages for the cyclist who has chosen Fulcrum.

- Anti-Rotation System

This system positions the concept of radiating to a new level of performance. In fact, Fulcrum technicians have redesigned the spokes and hub seats to create a solid and immovable set. In this way the radios:

a) they never lose their initial tension, thus keeping the wheel perfectly reactive and centered

b) will remain in the position studied in the wind tunnel, to ensure the best possible aerodynamic penetration

- 3Diamant: Surface treatment for friction surfaces

The result of this research is the new 3Diamant surface treatment that, thanks to advanced machining and precision diamond-tipped tools, eliminates imperfections caused by eventual non-uniform resin deposits and allows the pads to act directly on a fiber fabric. specifically designed carbon fiber. The new machining process also eliminates the need for a "break-in" period, improves overall braking performance in both dry and wet conditions, and generally produces more progressive and consistent braking.
