Fast Forward Carbon F6R Tubular 60mm SP WheelsetThe Fast Forward Carbon F6R Tubular 60mm SP Wheelset provides superb versatility and exceptional aerodynamic performance. Featuring exceptional stiffness and superb rolling finesse; the 60mm DARC profiled rim provides top-level aerodynamic stability and speed enhancing performance.Exceptional PerformerThis wheelset offers exceptional aerodynamic performance and stability, and you will now be able to tackle corners at much higher speeds. Thanks to the DARC rim profiling, crosswinds are managed very well and do not affect wheel and bike stability. This wheelset is a truly exceptional performer, just waiting to increase your race times, confidence and enjoyment from cycling.Features: Material: Rim: Carbon; Hubs Aluminium Rim Depth: 60mm Rim Profile: DARC Braking Surface: CBT BBS Spoke Count: Front: 20; Rear: 24 Spoke Type: Straight-pull Hubs: DT Swiss 350 Freehub: 11-Speed Weight: 1.38kgTechnologies: DARC: DARC technology is short for 'Double Arc' which refers to the profile of the rim. The revolutionary DARC profile improves aerodynamics dramatically by reducing the drag. Air has the characteristic to stick to its surface and by creating a negative arc section the air will be compressed more at the positive section. This will increase the pressure just like on the topside of an airfoil. Increased pressure results in a faster airflow and less resistance on the wheel which reduces the drag and increases the speed. Carbon TC-35: The Carbon TC35 is a material characterised by its high strength. This is important in a wheel to add durability and an extra level of stiffness to the wheels which makes them easier to turn. The wheels are therefore super robust and superior to other wheels made of other kinds of carbon. This level of durability makes them highly capable at being used in a variety of different environments. Confidence Brake Technology (CBT): FFWD Wheels applies three different brake track layers depending on the type of rim or type of use. CBT i: All FFWD tubular (road) rims have a Basalt brake surface (BBS). Reducing heat production and improving brake performance in combination with the supplied SwissStop black prince brake pads.Buy Fast Forward Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
