A minimalistic design out of the darkness. 
The Racing Zero family welcomes a new member: the Racing Zero CMPTZN DB!
We are excited to introduce this lighter aluminum disc brake variant that benefits the most minimalist look in the Fulcrum range. This strong and responsive wheelset features CULT bearings and the classic 2:1 spoke pattern with oversize double butted aluminum parts. The 30 mm 2-WAY FIT Tubeless profile aluminum rim, entirely manufactured in Italy, has a unique design, light and easy to handle. Both hubs feature oversize flanges to optimize the offset of the aerodynamic aluminum spokes. 
Thanks to all these innovations, the CMPTZ is now a big-impact addition to the Racing Zero DB model!

Features

2-Way Fit - profile for tubeless and clincher. Tubeless technology was first used by the auto industry, then by motorcycles and now has reached the cycling industry. After its debut with mountain bikes the moment has come to “put it on the road”, and that’s what Fulcrum propose to do. 

They have developed their 2-Way Fit technology to ensure the perfect compatibility of Fulcrum tubeless rims with normal clincher types and tubes. 2-Way Fit road bike wheels are perfectly multipurpose for tackling every situation. Thanks to a special impression in the valve area, the tubes are fitted with the maximum precision while keeping the tube perfectly stable inside the tyre.  Housing the valve for tubeless tyres is also risk-free, with the unquestionable advantage that there are never any air infiltrations caused by non-ideal positioning when fitting.

Ceramic Ultimate LeveL Technology (CULT) - Behind this project is the exclusiveness of Cronitect steel, using “Advanced by FAG” technology by Schaeffler Group employed for the bearing races. This steel is resistent to the corrosion of the highest level until the point that no grease is necessary for lubrication, maybe just a small amount of oil. The top quality ceramic balls, thanks to the absence of lubricating grease and the precision machine of the cup and cone technology, allow to reduce the friction coefficient drastically and then increase the smoothness of triathlon and road bike wheels by as much as 9 times compared to standard bearings. An outstanding result achieved by using cutting-edge technologies in the field of materials processing.

Rim Dynamic Balance (RDB) - For those who always want the next best thing, in range and performance, moving up the Gran Fondo rankings. Fulcrum might say it is the fastest ever aluminium Racing Zero – the perfect definition! A breathtakingly smooth run (thanks to CULT technology). This rim is born to take on the bends, without giving a centimetre. “Competizione”, for the truly competitive.

2:1 Two-To-One - 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.

2:1 Two-to-one Spoke Ratio - Disc Brake -

Drsc - Directionated Rim-spoke Coupling - 

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

Anti-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 (FIC) 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.

Tracebility - A guarantee of quality. The keyword for Fulcrums 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.

One HUB Fits All

Wide Rim Tech - Fulcrum’s R&D department, following requests from the competition circuit, has worked to create rims that are wider than before, about 4mm or more than previously. This technical choice provides an ideal basis for 25/28mm tyres, the sizes currently popular. This ensures stability, excellent handling and superior comfort.

Undrilled Rim Bed - No holes on the bridge connector means that the rim is uniform at every point, free from critical areas subject to stress.
The advantages are immediately clear: less weight, longer lasting rims, greater resistance to fatigue, the possibility of giving the spokes more tension and more stiffness which, in terms of performance, means improved responsiveness and acceleration.

Cup and Cone - The cup-and-cone bearing differs from the classic cartridge bearing because it works in perfect alignment with the forces involved, weight and thrust from the frame, as the bearings run in a race positioned directly opposing these forces.

Disc Specific Rim

High Strength Aluminum - Special aluminium - the best aluminium wheels require carefully chosen materials. For "High strength Aluminum", Fulcrum R&D uses only the best aluminium alloy 6082, with artificial ageing T6 temper that stabilises the alloy and gives it maximum life and reliability.

Aluminium 6082 has the highest strength of the 6000 series and has replaced 6061 in many applications. It is generally used for high-stress applications.

Carbon Hubs - In line with their aim to save every possible gram of weight and to choose the most advanced technological solutions, the R&D department has developed a seamless carbon hub. The fibre selected is woven at 90 degrees, for enhanced balance of torque when pedalling.

Plasma Freehub - The Plasma treatment makes the aluminium especially hard and resistant to surface abrasion and wear. This has allowed thickness of materials to be reduced to a minimum, achieving advantages of lighter weight, while maintaining lifespan and reliability.

Oversize Flange - The Oversize Flange was developed from the need to create a system to transmit every watt to the ground without dispersion, stiffening the wheel system where necessary, without having to add spokes or superstructures that increase weight.

The oversize flange uses physics to solve the problem. It increases dishing and enables spokes to be shortened. Doubling the spokes creates a balanced system that is excellent at transmitting torque.

Monoblock Hub for Disc - The rear hub of a top-quality disc brake wheel is a technical problem to be solved. Fulcrum’s R&D department found itself facing a fundamental choice: on which side to put the oversize flange of the Two-to-one system? Disc or sprocket side? Without question - must stay on the sprocket side.
To combat the loss of braking power from flex and torque of the connector between the two sides of the hub, a special one-piece system has been devised with internal stiffening ribs.

Specific Nipple Housing - 7% more reliable.

Such a small part, yet so important. The nipples and their housing are one of the most important element that are taken into account during the design of a wheel.

During the development of the new E-Mtb Fulcrum rims, a lot of work was put into this aspect. The housing has been re-designed and now it makes it possible to eliminate completely the nipples' hard work.

Thanks to a special housing, with side guides on both sides, the nipple sets on a stable base, perfectly in position, oriented towards the spoke.

This makes it possible to make the distribution of the tensions in the rim more even, creating thus perceptible benefits in terms of effort and rigidity: this prevents misalignments under stress and, as a consequence, deformation to the structure.

About The Brand

Since 2004, Fulcrum has developed wheels for bikes with a sole, constant objective in mind: to deliver the best performance that modern technology can offer.

A large part of this task is the responsibility of the R&D division engineering team in Italy. However, if you want to create even faster wheels, you cannot focus solely on test bench results, you also need to gain feedback from top riders and cycling fans worldwide.

And this is what Fulcrum has done: They race their bikes during lunch breaks or after work, test their wheels by pushing them to the max, fitting them to the bikes of world champions, listening to suggestions and comments from the world of racing and from their clients.
