Descriere Roata SET ROTI FULCRUM RACING QUATTRO LG Ax QR/QR Negru de la Fulcrum Cod producator: R4-16CFRBS1
35mm is not just any number.Fulcrum has developed the Racing Quattro to offer the rider perfect balance and performance in all situations. An aerodynamic yet easy to ride wheel that is ideal for long level straights, but still delivers outstanding results uphill. Versatile and aggressive, a wheel created for riders who enjoy pitting themselves against a different type of route every day.The Racing Quattro LG represents the family's aluminum version and despite its wider stance of 17C (23mm external) the Fulcrum engineers were able to produce a complete wheel that comes in at the exact same weight as the previous model. Increased stiffness, reactivity and greater stability along with a wider stance and housing for larger tires all with no weight penalty make this aluminum wheel perfect for long days in the saddle.Oversized hub body in aluminium provides a high degree of lateral stiffness and reduces the weight to a minimum. Adjustable ball bearing system in ultra high quality steel for reduced friction and maximum performance even after extensive use. Quick and easy to adjust. Aluminium axle reduces the overall weight of the wheel. Oversized flange on the drive side provides greater torsional stiffness, increases reactivity at any change in rhythm of the pedal stroke. Exclusive processing system of the 5 axis hub. This allows the spokes seat to be created perfectly in line with the tensioning line. This solution allows equal tension values to be obtained at every point of the spoke; it reduces stress on the rim and the spokes and keeps the wheel balanced.The 16 steel front wheel spokes are straight, aero and featuring an innovative anti-rotation system that keeps the spokes in an aero position at all times. The rear wheel has a 2:1 Two-to-One™ ratio, (7 2.2/2/1.6/2 on the left- 14 2/1.8/2 on the crankset side) that helps keep force balance on both sides of the wheel. Spokes are straight, aero, made of steel, and with an anti-rotation system.New 35mm rim. Developed to strike the perfect balance between aerodynamic efficiency, handling and lightness. The 35mm rim profile increases torsional and lateral stiffness compared with a conventional profile, for improved high speed stability.MoMag™ allows the external profile of the rim to be free of holes - increases structural resistance - makes rim tape unnecessary and reduces the weight of the wheel.Including steel spine and eccentric, lever with drill lightening and aluminum die. The eccentric-closure system allows cyclist to modulate the pressure necessary for heightened sensitivity to find the proper closure for the block. Easy to use, with a material resistant to wear and tear, rust, and pressure.S.H.A.R.C.No two wheels are alike, and no two riders. This is why Fulcrum, in collaboration with professional racers as well as amateur enthusiasts, has identified and developed the five most significant indicators that will allow you to choose the best wheel for your riding style and your needs. On a scale of 1-10 the Fulcrum Racing Quattro wheelset has received the following rating:S. = Smoothness: 8,5H. = Handling: 8,5A. = Aerodynamic: 9R. = Reactivity: 8C. = Comfort: 8,5An overview of the S.H.A.R.C. classification you will find under attachments.Note: For Campagnolo 9/10/11-speed or Shimano 9/10/11-speed systems (Shimano 10-speed only with 1 mm spacer which is included with the cassette).The included quick releases are not suitable for full carbon drop-outs!Product Name:Fulcrum Racing Quattro LG Wheelset - ClincherManufacturer:FulcrumYear:2018Manufacturer item code:Shimano: R4-16CFRBS1Material:rims: aluminumhubs: aluminumspokes: stainless steelWeight:approx. 1766 gram (approx. 806 grams (front wheel)approx. 960 grams (rear wheel weighed)Rim height:35 mmexternal/internal rim width:external: 23.2mminternal: 17mmE.T.R.T.O.:17-622Spokes:aero stainless steelNipples:aluminumSpokes number:front: 16 (radial)rear: 21 (left: 7 radial - right: 14 crossed)Hub axle system:front: 100 mmrear: 130mmFitting type of tire:clincherFitting tire dimension:width: 25mm - 32mm (manufacturer recommendation)Purpose:Competition, TrainingFitting for shifting:optionally:Shimano 8/9/10/11-speed HGMax. permissible total weight(rider + bike):109 kg (rider)Included in delivery:wheelset (FW & RW), spacer (HG version only), quick releases
