Campagnolo EPS Record 11sp Ergopower Road Shifters EPS Ergopower controls represent the direct "electronic" evolution of the well-proven mechanical Ergopower.Maintaining the special features, unaltered, the operating philosophy (one lever one action), Campangolo's trademark click feeling, Multishifting technology for the rear derailleur lever, the excellent ergonomics, the comfort of the brakes and the extreme braking efficiency.Features: The Mode Key: In addition to the 3 classic levers, the EPS Ergopower controls are equipped with what is known as a MODE key. By pressing on it briefly you can view the battery charge level, whereas by pressing on it longer you will enter adjustment mode without ever taking your hands off the controls. Comfort: The shape places the levers in a position that is easy to access at all times, without any effort at all, regardless of the steering position and whatever the size of your hands. By studying the positions of cyclists' hands, in fact, there were found to be 3 different riding positions depending on the route and riding style itself. These studies made it possible to create the special and exclusive shape of the EPS Ergopower controls, which unlike the mechanical controls, are equipped with a dedicated hood and the control body is made from a very new material that is more rigid and lighter. Effective Braking: The Ultra-Shift(TM) shape of the levers, as with the mechanical controls allows you to act on the brakes more powerfully. When you have a high grip on the handlebars, especially, it is possible to put the brakes on with more power and faster. Click Feeling: The levers simulate the classic Campagnolo Click Feeling thanks to the application of MultiDome technology. DTI: Digital Tech Intelligence is housed inside the Power Unit and it continuously monitors the signals that arrive from all the EPS components, thus managing their operation. Multi-Shifting: There are no longer any limits to Multi-shifting and the choice is at the fingertips of the cyclist. Zero Settings: The procedures to reset the rear derailleur and derailleur to zero are essential for the system to function. Riding Settings: The client can adjust the reference position of the rear derailleur and/or derailleur using the adjustment procedure known as Riding Setting. One Lever - One Action: The EPS system CONTROL levers are positioned and act according to the same logic as Campagnolo mechanical gear levers. E2 Ergonomy: The design of the body of the control conforms perfectly to your hands. Water Proof: In order to achieve the IP67 classification, all the electronic components of the EPS system underwent a series of tests, which proved their ability to function perfectly under one meter of water for at least 30 minutes. WARNING - All connection, installation, removal and adjustment operations of the EPS drivetrain must only be carried out by a Campagnolo Service Center, a Campagnolo Pro Shopor a mechanic specializing in the installation of EPS systems. Any Tampering with or incorrect or incomplete installation of any part of the EPS system will automatically void the warranty. NOTE FOR SPECIALISED MECHANICS - Please remember that all assembly, disassembly, adjustment and maintenance procedures for the EPS drivetrain are described in the EPS technical manual, which is available in PDF format on our internet site www.campagnolo.com.

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: CPW5220DA Brown Dark Copper Shaded 700c Shimano/SRAM CPW5220D Brown Dark Copper Shaded 700c Campagnolo CPW5220DB Brown Dark Copper Shaded 700c SRAM XD Sram XDRBuy Campagnolo Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
