Fulcrum Racing Zero 2-way Fit (pair):

Red spokes, black rims: wheels that are absolutely unmistakeable in the middle of the peleton. Two powerful colours and exclusive technology stand out from the crowd and make these wheels unique in terms of performance and personality. Racing Zero wheels are at the top of the Fulcrum® range.

The 2-Way Fit- (Tubeless & Clincher) version is fitted without tubes, mostly to the advantage of safety and comfort but also in terms of performance. This is an advantageous product which offers a double choice, allowing you to choose the benefits of tubeless or the practicality of clincher tyres.Thanks to Ultra-Fit -Tubeless technology, the use of the tubeless tyres drastically improves smoothness and reduces the risk of snake biting on rough roads. The release of air is also gradual in the event of puncturing: there is no risk of sudden deflation.

The rim is made using a special extrusion procedure which thins the walls. At the same time, the 26 millimetre thickness is a guarantee of strength. A rim of this type is excellent in terms of resistance and weight.
Further lightening has been obtained by milling the material between the spoke anchoring points while the rim is perfectly balanced thanks to Dynamic Balance- technology.

The spokes are made of aluminium with an aerodynamic profile. There are 16 in the front wheel, radially laced; 21 in the rear: 7 on the left and 14 on the right, in accordance with Two-to-One- technology.

The hubs with carbon body and alloy axle are now equipped with USB- ceramic bearings that increase smoothness, prolong service life, and further reduce the weight of the wheels.

Racing Zero 2-Way Fit- wheels are compatible with Campagnolo®, Shimano Inc. and Sram Co. drivetrains.

Nominal weight (The weight of the wheels does not include the quick release, and it refers to the lightest configuration):

- Front: 625 g

- Rear: 835 g

Ultra Torque-
-On the wave of success obtained by the Racing Torq- R and Racing Torq- RS models, this years range is enriched by the Racing Torq- RRS which uses innovative CULT- ceramic technology.

The Ultra Torque- axle assembly is inside the bottom bracket shell in order to reduce lateral bulk. Its life over time is increased by the new anodization treatment which also comes with a darker and more aggressive colour. Compatibility with the most common drivetrains is ensured.

Ultra-Fit- Tubeless
-Heres the interface between the tubeless tyre and the rim. The form we have studied for our rims with Ultra- Fit- Tubeless technology means that the sides of the tyre mate perfectly with the shoulders of the rim when it is fitted. The result is exceptionally smooth: for whizzing speedily without tubes!
By eliminating every possible movement between the rim and tubeless tyres, all energy dispersion is also eliminated. The Ultra Fit- Tubeless wheels well exceed any other wheel fitted with traditional tyres in our tests.

The first installing of the tyre is also made with great ease: two special tracks on the rim groove keep the tyre perfectly in position.

2-Way Fit-
-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 thats what we propose to do. We have developed our 2-Way Fit- technology to ensure the perfect compatibility of our tubeless rims with normal clincher types and tubes. 2-Way Fit- 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.


The advantages are indisputable: our tests have highlighted an unique increase in smoothness. Because there is no tube, the friction caused by rubbing against the tyre is eliminated, while the perfect adherence of the tyre to the rim prevents the dispersion of energy.

Tubeless tyres do not suffer from sudden deflation when punctured which is a great advantage in safety terms. There is also no risk of snake bites as there is no tube to rupture.

What if a tubeless tyre gets punctured- Theres nothing to fear...With Fulcrum® 2-Way Fit- you can remove the tubeless valve and fit in a standard clincher tire that will let you ride back home.

Cult-
-Ceramic Ultimate Level Technology, CULT-. It-s the technical advancement adopted for the most revolutionary crankset in the Fulcrum® range, the Racing Torq- RRS, an unprecedented system which guarantees performance at the maximum level. As well as using the best ceramic ball bearings on the market, a new treatment for the races and bearings has been developed with Cronitect® steel, using the "Advanced by FAG" technology by Schaeffler Group.

Maximum corrosion resistance, no grease is necessary for lubrication, just a small amount of oil.


CULT-: it stands for Ceramic Ultimate Level Technology. But, above all, it is the technology we have developed, fine-tuned, and then adopted exclusively for the realization of the bearings with ceramic balls.

Behind CULT- is the exclusiveness of Cronitect® steel, using the "Advanced by FAG" technology by Schaeffler Group., for the bearing races.

This is an incredibly robust and corrosion-resistant stainless steel, with a surface thermo chemical treatment that makes it extremely resistant to corrosion.

The final result- Amazing: wheels with CULT- ball bearings are 9 times smoother than wheels with traditional bearings. A benefit that translates into a great advantage when it comes to saving energy and seconds or even minutes.

CULT- is on Racing Light XLR, Racing Speed XLR and Racing Chrono.

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 te nsion. 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.

As a result there are two spokes which carry out the function of one, slackening and torsion are limited and the transfer of the athlete-s power is much more effective Also, thanks to this system, spoke tensions are balanced more evenly between drive and non-drive sides and the fatigue life of the rim, hub and spokes is lengthened.

Dynamic Balance-
- The concept is simple and elegant: balance the weight of the gasket, with an item of similar weight placed on the exact opposite side.
For top models, this is obtained by a special operation on the section of the rim opposite the rim joint.
For entry-level models, Dynamic Balance- is obtained by using two oversized spokes in the section opposite the joint. The result is a wheel with perfectly balanced rotational dynamics.

MoMag-
- Though they have no holes in the rim bed, Racing3, Racing1 and RacingZero rims have spokes tensioned by traditional nipples. This makes tensioning and changing the spokes extraordinarily easy, and does away with questionable anchoring systems on the rim.


This solution was made possible thanks to the Fulcrum® MoMag- patent which exploits magnetic power and a good dose of ingenuity to guide the nipples to the correct rim holes.

Spoke anti-rotation system
- This new system raises the concept of spoking to new heights of performance. 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, and b) will remain in the position that was found in wind tunnel tests to ensure the best aerodynamic penetration possible.

The spoke antirotation system comes in all: Racing Speed and Racing 3 2WF

Maximum Compatibility
- With the new Fulcrum® freehub body dedicated to non-Campagnolo® drivetrains you will be able to exploit the maximum versatility of your current system. We have developed a freehub body that is perfectly compatible with Shimano Inc. 8, 9 and 10 speed systems and Sram Co. 10 speed ones.


USB-
-The high quality smoothness of Fulcrum® wheels is a universally recognised fact. The decision to produce our own bearings rather than using standard ones has resulted in performance and service life unequalled on the market.

For this technological solution Fulcrum® chose the best ceramic balls available on the market - Silicon Nitride (Si3N4) - so compared to the already extraordinary quality of the steel ball bearings normally used by Fulcrum®, USB- bearings have truly astonishing features:

- 30% lighter
- 40% more resistant
- 50% smoother

USB- is in all our Racing Zero models.

WRS
-What is the ideal wheel-

This is the question that every rider asks before buying a wheel - and Fulcrum® wants to help you find an answer!

This is why, in collaboration with professional riders and cycling enthusiasts, we have defined the 3 most important parameters that will enable you to choose the best wheel for your riding style and needs.

What does W.R.S. mean-

Weight: There is little need to describe it. The weight of the wheel is the first question that all riders ask themselves when they buy a wheel.
The weight parameter is extremely important, more than any other bike component. Indeed the wheel is a rotating mass and as such it follows the laws of physics that determine its acceleration and inertia.
Fulcrum has always designed its wheels with this aim in mind and, at the same time, combining and adapting it to wheel performance in terms of the stiffness, reactivity and reliability.

Reactivity: How -ready- and fast does the wheel feel every time you change gear- The level of reactivity refers precisely to this concept.
Reactivity depends on the weight of the rim and of the wheel as a whole, on torsional rigidity (i.e. how much the wheel flexes around the hub when the rider pushes on the pedals), on flexional rigidity (i.e. how much the wheel maintains its shape if, because of pedalling, it moves away from its vertical axis) and on inertia.

Smoothness: This will help you understand and compare various wheels degree of smoothness, thanks to, the use of high-performance CULT- ball bearings or USB- ball bearings or to other technological solutions applied on the wheel, such as 2-Way Fit-.

Fulcrum® gives you all the technical information, now it-s up to you to choose the perfect wheel for your needs! Your passion, your way of riding the bike and your feel of the bike will help you to make the best choice.
