Kuvaus - Polkupyörän pyöräsarja Fulcrum Racing 3 DB C19 2WF AFS front HH12 + KIT HH15 - rear HH12142

How many times have you imagined a set of all-purpose wheels, excellent in the winter, agile and performing uphill, with no limits on less-than-perfect road surfaces, reliable and ready when you need to concentrate exclusively on your training, and a loyal companion when your goal is big mountain passes, great distances, and big adventures?

Racing 3 DB is a concentrate of technology designed to raise the performance bar in a wide range of situations, setting new standards for satisfaction and reliability. The focus here was on substance and the R&D division at Fulcrum have taken everything to a higher level, choosing the most balanced, evolved a technical solution for every single essential component. Extremely smooth thanks to the cone and cup bearings and comfortable thanks to steel spokes that ensure 25% more shock absorption. The 19 mm wide well also ensures generous, robust, stable contact with the road. "Versatility" for Racing 3 DB means making the difference whatever the context: as a training wheel, for long distances, and on gravel. It is also a high-class upgrade for those who enjoy cycling without any competitive intent. Good-looking, refined, detail-attentive construction.

2-WAY FIT (ROAD): 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 Fitroad 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.

RDB RIM 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.

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.

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 ( and mtb too) 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.

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.

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 4 mm 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.

CUP & 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. The adjusting ring lets you pre-load the bearing, so you can eliminate side-to-side play and have optimum adjustment once the wheel is mounted on the frame.

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.

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.
