Fulcrum Racing Speed XLR Carbon Tubular 11s Road Bicycle Wheelset

Racing Speed wheels are much loved by professional cyclists. Their widespread diffusion is due to the wheel's many features: the high rim profile combined with lightness make this model particularly suitable for the most varied racing situations. In the Racing Speed XLR version the hub body is made of carbon. The balls of the bearings implement CULT technology with its super high strength and smoothness thanks to CronitectR stainless steel with thermo chemically treated surface layer. The rim has a 50 millimetre profile and is supported by 18 radially laced spokes in the front wheel and 21 in the rear with doubling on the freehub side using Two to One technology.The carbon rims are made using a particular technique by which the carbon fabric is aligned so that the resulting rim is always balanced.The use of pads for special brakes is necessary supplied. Racing Speed XLR is compatible with CampagnoloR, Shimano Inc., or Sram Co. drivetrain systems and are supplied with the new FulcrumR quick release.Nominal weight:front: 577 grear: 747 g
