The answer was the use of 24 aerodynamic flat spokes designed specifically for this wheel and laced using the Two-to-One™ system, which involves doubling the spokes in the areas subject to the greatest mechanical stress. \u003cbr\u003eThe front wheel therefore has 16 spokes on the disc side and 8 on the other side, while the rear wheel is constructed in the opposite manner to counteract the forces developed by the drivetrain. This specific construction, combined with the perfect tensioning of the spokes, gives the wheel a torsional rigidity that enables maximum force transfer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRedesigned hubs  \u003cbr\u003e\u003c\/strong\u003eThe novelties also concern the hubs, which have been completely redesigned to accommodate a freewheel mechanism that is more precise than the previous one while reducing weight.\u003cbr\u003eThe bearings used for the Fulcrum Speed 42 and 57 are of the cone-cup type and use the USB™ (Ceramic Ultra Smooth Bearings) system with ceramic balls, which guarantees unparalleled smoothness.\u003cbr\u003eThe freewheel rack has been reinforced and oversized and now houses 36 teeth. The wheel is available in configurations with Campagnolo N3W, Shimano HG and Sram XDR bodies.\u003cbr\u003eAll these innovations have a single objective: to convey the perfect riding sensation that can only come from the balance between lightness, drivability and aerodynamics. \u003c\/p\u003e\n\u003ch2\u003e\n\u003cbr\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFull carbon aero profile: 42 mm \n\u003c\/li\u003e\n\u003cli\u003e2-Way Fit Tubeless - Undrilled rim bed \n\u003c\/li\u003e\n\u003cli\u003e23 mm inner rim width \n\u003c\/li\u003e\n\u003cli\u003eUSBTM - ultra smooth ceramic bearings \n\u003c\/li\u003e\n\u003cli\u003eEngineered in italy - Made in EU \n\u003c\/li\u003e\n\u003cli\u003eReal pair weight: 1430 g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n\u003cbr\u003eTechnologies\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003e2-Way™ Fit\u003c\/strong\u003e\u003cbr\u003eTubeless technology was adopted in the automotive sector, then in the motorbike sector and finally in cycling. After its debut in mountain biking, it's time to \"put it on the road\": and that's what Fulcrum offers. It has developed 2-Way Fit™ technology to ensure the perfect compatibility of their tubeless wheels even with normal clinchers and inner tubes. 2-Way Fit™ wheels are perfectly multipurpose for tackling any situation. Thanks to a special indentation in the valve area, the tubes are fitted with maximum precision, keeping the tube perfectly stable inside the clincher. The valve for tubeless tyres is also accommodated without risk, with the undoubted advantage that there is never any air infiltration due to sub-optimal positioning during assembly. The advantages are clear: various tests have shown an unprecedented increase in smoothness. As there is no inner tube, friction due to friction with the tyre is eliminated and the perfect adherence of the tyre on the rim avoids energy losses. A tubeless tyre does not suffer from sudden deflation in the event of a puncture, so that's a nice safety advantage. No risk of pinching, then, because there is no inner tube to break.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUSB™ Ceramic Ultra Smooth Bearings™\u003c\/strong\u003e\u003cbr\u003eFulcrum® has always been recognised for the extremely high performance of its hubs in terms of smoothness and reliability.\u003cbr\u003eThis is because all projects are developed in-house in the Fulcrum® R\u0026amp;D department and every detail is taken care of with obsessive attention. Hubs equipped with USB™ ceramic bearings (Ultra Smooth Bearings) further enhance the wheels' smoothness and reduce weight and maintenance, making your racing bike wheels faithful allies.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUndrilled rim bed\u003c\/strong\u003e\u003cbr\u003eThe absence of holes in the upper deck means a product that is homogeneous throughout, free of critical points subject to stress. The advantages are immediately perceivable: less weight, longer rim life, greater resistance to fatigue, the possibility of tensioning the spokes more and greater stiffness which, in terms of performance, mean more reactivity and acceleration.\u003c\/p\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/9MxUqnG5WZY\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen\u003e\u003c\/iframe\u003e","brand":"Fulcrum","offers":[{"title":"Shimano","offer_id":48058845331697,"sku":"RS-23DCFRAS","price":1963.6,"currency_code":"AUD","in_stock":true},{"title":"Sram XD-R","offer_id":48058845364465,"sku":"RS-23DCFRAX","price":1960.46,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/1580\/4145\/files\/zm_20230428-101805.jpg?v=1776539410","url":"https:\/\/novasportsbikes.com\/products\/fulcrum-speed-42-db-2wf-c21-afs-wheelset-1","provider":"Nova Sports Bikes","version":"1.0","type":"link"}
