Description

About Fulcrum Racing Quattro Carbon Clincher DB

Whatever the situation, the promise is to become the ideal ride companion every day. 

Thanks to its magical balance, the new 40 mm profile of these road bike wheels will do credit to itself on any road you tackle together. 

Performance? It's aerodynamic, stable and fast. Climbs? It stays light and reactive when accelerating. 

Downhills? It's decisive and easy to handle. 

Racing? It's simple - just try it!

Technologies

Rim Dynamic Balance (RDB) - The concept is simple and elegant: balance the weight of the gasket, with an item of similar weight placed on the exact opposite side.

2:1 Two-to-OneWhen 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.

2:1 Two-to-One Spoke Ratio - Disc BrakeA system that is as simple as it is effective, the result of the ingenuity of Fulcrum engineers and attentive observation of the results of the tests performed on the wheels on a daily basis.

These tests made it possible to understand that the forces that act on the sides of the wheels, and therefore on the spokes, are extremely different; but what’s more, the differences between the front and rear wheels are also evident and significant. The front wheel, in fact, has to remain stable even during braking of the disk on the left side, and the rear wheel, in addition to the sprocket set, has to compensate for the traction of the force on the chain side.

DRSC - Directionated Rim-Spoke Coupling - Exclusive rim/spoke coupling system. It allows the rim, spokes, nipples and hub to align properly with the same tensioning value in all areas.

MOMAG What is MoMag? A magnet and lots of ingenuity. This was what led to the patent for the well-tested “Mounting Magnet” system, or MoMag.

Anit-Rotation System 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 

a) will never lose their initial tension, thus keeping the wheel perfectly reactive and centred

b) will remain in the position that have been studied in the wind tunnel tests to ensure the best aerodynamic penetration possible.

Fulcrum Identification Card - 100% Handmade Quality Right from its inception Fulcrum® has been marked by feature that continues to this day: that is to design, prototype and industrialise all the wheels characterised by the red “F”.

Indeed these take shape inside of the R&D, the leading-edge department that represents the beating heart of the Italian company.

Every single component of the wheel, the materials chosen and the technologies applied are the tangible result of the effort that Fulcrum makes every day to give you maximum performance and reliability.

Traceability A guarantee of quality

The keyword for their products is: traceable. 

If you find a little label attached to any Fulcrum product, do not remove it. It will provide you a guarantee in case of an ascertained defectiveness of a production batch, and so the component needed or wheel will be traceable.

All this because, devoted to its mission, Fulcrum demands the absolute perfection and safety for its customers.

AFS Axle System - The Axial Fixing System is the solution developed by Fulcrum® to fix the disc brake to the hub. The constraint granted by the butt area of the release mechanism, greater than in familiar standard ones, makes it possible to obtain greater structural rigidity and therefore more precise and powerful braking.

Features

Rim - Carbon road bike rims, a combination of UD-unidirectional fiber with 3K inside. 40 mm high, wider cross section: ETRTO 17C, 24.5 mm outside width.

Disc Brake Hubs - Disc brake hub with oversize aluminum flange and Two-to-One technology to transmit all the power to the ground.

Oversize Flange - Aluminum hubs with oversize aluminum flange and Two-to-One technology to transmit all the power to the ground.

Spokes and Nipples - Variable aero spokes in steel, aluminum nipples.
