With 2-Way Fit, Campagnolo customers will be able to personally test which of the two solutions suits them best or use the clincher for training and the tubeless tyre for the day of the race. With no doubt, tubeless tyres are the future of road cycling. Apart from greater comfort, the advantages are many: using a tubeless tyre you can exploit the greater smoothness due to the absence of friction between the tyre and the tube. There are no risks of sudden deflation when a tubeless tyre is punctured, a great advantage in safety terms. The lack of tubes eliminates puncture risks. And what if the tubeless tyre has a puncture? The Campagnolo 2-Way Fit system allows you to use a traditional inner tube by simply removing the hermetic closure valve to ride home with no problem. CULT Bearings: Ceramic Ultimate Level Technology (CULT) is the combination of the highest quality ceramic ball bearings and stainless-steel races available on the market, in other words, the technological excellence that makes Campagnolo brand products stand out. Ceramic ball bearings make it possible to reduce friction to the minimum and maintain consistent performance over time. Bearing races in stainless steel, with thermochemical surface treatment, make the sliding surface of the bearings on which the ceramic balls rotate, extremely hard and resistant to wear. This Campagnolo solution, covered by specific patents, reduces wheel and crankset friction to a minimum, thanks to two characteristics that only CULT technology offers: the lubrication system, just a film of oil instead of the usual grease, and a structure that is totally impervious to dirt, so much so that Campagnolo components using CULT technology have no need for dust protectors. The result? The smoothest, longest-lasting ball bearings on the market! Try them! G3 Pattern: Campagnolo has developed an assembly architecture that, compared with a traditional wheel, makes it possible to improve energy transfer, reduce the stress on the spokes on the right and increase transverse rigidity. This is achieved because in G3 geometry the right-hand side of the rear wheel is fitted with twice as many spokes as the left. The results of G3 system are truly extraordinary: better transfer of the driving torque, better lateral rigidity, reduction of the stress in the rear wheel spokes. And thanks to the G3 system that compensates for the forces acting on the two sides of the wheel, there are no more wheel vibrations, even for heavier people.Manufacturer's Part Numbers: CPW5240DA Brown Dark Copper Shaded 700c Shimano/SRAM CPW5240D Brown Dark Copper Shaded 700c Campagnolo CPW5240DB Brown Dark Copper Shaded 700c SRAM XD Sram XDRBuy Campagnolo Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.

Our Reacto has always been a class leading aero bike, combining state of the art aerodynamics and comfort. The 4th generation Reacto is more slippery and beautiful than ever, incorporating wider tyres and much neater cockpit cable integration. With its predecessor delivering almost unrivalled aerodynamic performance we had to look at the smallest incremental improvements. Computational Fluid Dynamics (CFD) calculations modelled performance in a virtual wind tunnel to optimise aerodynamics guiding the changes which gave most aerodynamic benefit: New fork design, smoothly integrated into the frame, significant 2 Watt improvementNew handlebar design completely integrating the cables, saves about 2 watts per cableIncreased gap between the tyre and seat stays and between the tyre and fork crown and blades optimises airflow in those key areas. A lower junction between the seat stays and seat tube further reduces drag. Further small details such as integrating the front disc cooler behind the fork and the rear in the rear triangle and creating new through axles with the thread integrated into the fork dropout also minimise drag and improve aerodynamic performance. All these improvements enable us to over-compensate the aerodynamic compromises made to give the bike bigger tyres. The result: the perfect package of comfort, aerodynamic, lightweight and style. Prototypes were wind tunnel tested following the German TOUR magazine standard, including the ‘moving leg dummy’ test. The new Reacto needs just 209 watts effort for 45 km/h speed, 1 watt faster than its predecessor, and in the leading group of aero road bikes ever tested by TOUR magazine.The 4000 uses a CF3 frame, the same geometry and features, but with more economic fibres used in the carbon lay-up.
