Pair of Fulcrum Racing Quattro Carbon H40 wheels for QR axis tyre

The pair of wheels Fulcrum Racing Quattro Carbon H40 with Shimano Campagnolo core and QR axis seek to become the ideal companion of departures for every day, in any situation. A magical balance: the new 40 mm profile will shine on any road. The displacement is aerodynamic, stable and fast. In the rises it remains light, and it is reactive for the re-releases. In the descents, firm and dominable.

Features:
- Rim: carbon, a combination of UD fibre - unidirectional and 3K inside. Height 40 mm, oversized section: ETRTO 17C, outside 24.5 mm.
3K carbon braking track with 3Diamant treatment for maximum power and sensitivity in all braking conditions
- Weight: 1555 g
- Includes brake pads
- Hubs: Aluminium hub system with adjustable bearings made of high quality steel. Aluminium hubs with oversized aluminium flange and Two-to-One technology on the rear to transmit all the power to the ground
- Radios and ringlets: Aerodynamic radii of variable steel section. Aluminium rivets
- Compatible bushing: Shimano, Campagnolo

Technologies:
- Dynamic Balance
The concept is as simple as it is great: Weigh the mass of the rim seal with a mass of similar value positioned exactly on the opposite side. As for the 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 sheets so that the wheel is always balanced.

-Two-to-One
Fulcrum is recognized for the high performance of fluidity and reliability of its bushes. This is because all the designs are developed internally in the R & D department, and every detail is taken care of obsessively.

The bushes are equipped with USB ceramic bearings (Ultra Smooth Bearings), which 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. Raising the performance of your competing bicycle or simply pedalling 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 of the proven systemMounting Magnete, or MoMag.
How does it work? Once the spoke spokes have been inserted into the rim through the valve hole, they areguided 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 radiated tension by means of the rivets of the traditional radii.
Advantages: a rim without holes means a uniform rim in all its points, free of critical points or areas of breakage and, the cover profiles do not require the rim bottom, which offers important advantages in terms of weight. The advantages can be appreciated 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 radios, which is thus extremely easy and fast. All these are advantages for the cyclist who has chosen Fulcrum.

- Anti-Rotation System
This system positions the radiating concept at a new level of performance. In fact, Fulcrum technicians have redesigned spokes and bushing 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 centred
b) they will remain in the position that has been studied in the wind tunnel, to ensure the best possible aerodynamic penetration

- 3Diamant: Surface treatment for friction surfaces
The result of this investigation is the new treatment for surfaces 3Diamant that, thanks to the advanced mechanized and to tools of precision with tip of diamond, eliminates the imperfections caused by eventual deposits not uniform of resin and allows that the shoes act directly on a fabric of fibres carbon fibre specifically designed. The new machining process also eliminates the need for therolling period, improves the overall performance of the brakes both dry and wet and produces, in general, a more progressive and constant braking.
