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.Sepcifications:- Tyre Type: 2-way Fit (for Clincher And Tubeless)- Tyre Size: 28´´- Discipline: Road / Gravel- Astm Category: 2- Weight: 1660 g- Rim Material: Aluminum- Rim Material Details: Alluminio (6082, T6 Pre-aging), Square-milling- Profile Height: Low- Rim Height: Front And Rear: 28 mm- Rim Width: 23,8 mm- Inner Rim Width(channel): 19 mm- Tyre Width: From 23 Mm To 58 mm- Braking System: Disc Brake- Braking Surface/brakes Options: Afs- Front Axle Compatibility: Hh12-100- Rear Axle Compatibility: Hh12-142- Front Wheel Spokes: 21, Two-to-one (14 Left + 7 Right)- Rear Wheel Spokes: 21, Two-to-one (7 Left + 14 Right)- Spokes: Material: Stainless Steel, Double Butted- Spokes: Profile: Rounded, Straight Pull- Nipples: Aluminum- Front Hub: Aluminum, Aluminum Oversize Flange- Rear Hub: Aluminum, Aluminum Oversize Flange- Bearings: Adjustable Cup & Cones Bearing System- Others: Aluminum Axle.

After its debut with mountain bikes the moment has come to put it on the road, and that's 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™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.2:1 Two-to-One Spoke Ratio™ - Disc Brake:- A 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.MoMag™:- A magnet and lots of ingenuity. This was what led to the patent for the well-tested Mounting Magnet system, or MoMag™.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.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.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.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.
