Creating it wasn't easy, given the premises and the myth it referred to, developing a design along the same lines as that of conventional brakes. The riding experience is the same and equally exhilarating until you come to the extreme rush at a hairpin bend.\u003c\/p\u003e\n\u003ch2\u003e\n\u003cbr\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTyre type: 2-Way fit (for clincher and tubeless) \n\u003c\/li\u003e\n\u003cli\u003eTyre size: 28\" \n\u003c\/li\u003e\n\u003cli\u003eDiscipline: Road \/ Gravel \n\u003c\/li\u003e\n\u003cli\u003eASTM Categor: 2 \n\u003c\/li\u003e\n\u003cli\u003eReal weight: \n\u003c\/li\u003e\n\u003cli\u003eReal weight: \n\u003c\/li\u003e\n\u003cli\u003eRim material: Aluminum \n\u003c\/li\u003e\n\u003cli\u003eRim material details: Aluminum (6082, T6 Pre-Aged), triple milling \n\u003c\/li\u003e\n\u003cli\u003eProfile height: Medium \n\u003c\/li\u003e\n\u003cli\u003eRim height front and rear: 30 mm \n\u003c\/li\u003e\n\u003cli\u003eRim width: 23,8 mm \n\u003c\/li\u003e\n\u003cli\u003eInner rim width(channel): 19 mm \n\u003c\/li\u003e\n\u003cli\u003eTyre width from: 23 mm to 50 mm \n\u003c\/li\u003e\n\u003cli\u003eBraking system: Disc brake \n\u003c\/li\u003e\n\u003cli\u003eBraking surface\/brakes options: AFS \n\u003c\/li\u003e\n\u003cli\u003eFront axle compatibility: HH12-100 \n\u003c\/li\u003e\n\u003cli\u003eRear axle compatibility: HH12-142 \n\u003c\/li\u003e\n\u003cli\u003eFront wheel spokes: 21, Two-to-one (14 left - 7 right) \n\u003c\/li\u003e\n\u003cli\u003eRear wheel spokes: 21, Two-to-one (7 left - 14 right) \n\u003c\/li\u003e\n\u003cli\u003eSPOKES MATERIAL: Aluminum \n\u003c\/li\u003e\n\u003cli\u003eSpokes profile: Aero, straight pull \n\u003c\/li\u003e\n\u003cli\u003eNipples: Aluminum \n\u003c\/li\u003e\n\u003cli\u003eFront hub: Carbon, Aluminum oversize flange \n\u003c\/li\u003e\n\u003cli\u003eRear hub: Aluminum, Aluminum oversize flange \n\u003c\/li\u003e\n\u003cli\u003eBearings: USB ceramic bearings.

In fact, all the projects are entirely developed in our R\u0026amp;D department and we have put obsessive care into taking care of every detail. The hubs with USB™ ceramic bearings (Ultra Smooth Bearings) further enhance the triathlon and road bike wheels’ smoothness and reduce weight and the need for maintenance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2:1 TWO-TO-ONE™\u003c\/strong\u003e\u003cbr\u003eWhen 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2:1 TWO-TO-ONE Spoke Ratio™ - Disc Brake\u003c\/strong\u003e\u003cbr\u003eA 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMomag™\u003c\/strong\u003e\u003cbr\u003eA magnet and lots of ingenuity.

Fulcrum Identification Card - 100% handmade quality\u003c\/strong\u003e\u003cbr\u003eRight 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\u0026amp;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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTraceability\u003c\/strong\u003e\u003cbr\u003eIf 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAFS Axle System™\u003c\/strong\u003e\u003cbr\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWide Rim Tech\u003c\/strong\u003e\u003cbr\u003eFulcrum®’s R\u0026amp;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.

For \"High strength Aluminum\", Fulcrum® R\u0026amp;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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCarbon Hubs\u003c\/strong\u003e\u003cbr\u003eIn line with their aim to save every possible gram of weight and to choose the most advanced technological solutions, the R\u0026amp;D department has developed a seamless carbon hub. The fibre selected is woven at 90 degrees, for enhanced balance of torque when pedalling.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlasma Freehub\u003c\/strong\u003e\u003cbr\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOversize Flange\u003c\/strong\u003e\u003cbr\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMonoblock Hub for Disc\u003c\/strong\u003e\u003cbr\u003eThe rear hub of a top-quality disc brake wheel is a technical problem to be solved. Fulcrum®’s R\u0026amp;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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecific Nipple Housing\u003c\/strong\u003e\u003cbr\u003eThanks 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.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.fulcrumwheels.com\/en\/support\/download-area\/download-user-manuals\"\u003eHere you will find Product Catalogues, User Manuals, Technical Manuals, Video Tutorials and annual Replacement Parts Catalogues.\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/adapters.fulcrumwheels.com\/?id=1\"\u003eChanging the specifications of Fulcrum wheels.\u003c\/a\u003e\u003c\/p\u003e","brand":"Fulcrum","offers":[{"title":"Campagnolo","offer_id":48058845036785,"sku":"R0-20DFR22AC","price":989.44,"currency_code":"AUD","in_stock":true},{"title":"Shimano","offer_id":48058845069553,"sku":"R0-20DFR22AS","price":986.94,"currency_code":"AUD","in_stock":true},{"title":"Sram XD-R","offer_id":48058845102321,"sku":"R0-20DFR22AX","price":975.37,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/1580\/4145\/files\/zm_20230523-010211.jpg?v=1776539391","url":"https:\/\/novasportsbikes.com\/products\/fulcrum-racing-zero-db-c19-2wf-afs-wheelset-1","provider":"Nova Sports Bikes","version":"1.0","type":"link"}
