Campagnolo Potenza HO Road Shifter and Disc BrakeThe Campagnolo Potenza HO Shifter + Caliper provides exceptional braking power and shifting responsiveness. The level of speed and performance that is offered by many shifters and brakes on the market means nothing if the rider is not in control. The Potenza Ergopower features fantastic ergonomics meaning the shifting and braking commands feel natural in your hands and always ensure that you are in complete control in every situation.Comfortable and Consistent GripThe shifting controls and braking mechanisms have undergone in-depth studies to find the sweet spot for comfort and consistent grip over a long-distance ride. The ergonomic design also focus' on the natural motion of the human hand, meaning you can access the brake levers from above or below the hoods and will still provide exceptional braking power. Likewise, the up-shift and down-shift levers move in motion with how the human hand functions, making the whole process of using an Ergopower lever a pleasing and effortless experience.Features:Material: AluminiumShifter Type: Power-Shift mechanicalBrake Type: HydraulicLever Ergonomics: ErgopowerWeight: 370gTechnologies:Multishifting: Multi-shifting technology makes it possible to smoothly shift 5 gears down the cassette and 3 gears up by simply holding down the shift lever.Ergopower: Ergonomics: The shape of the shifter body conforms to your hands perfectly. The body of the control reproduces exactly the asymmetry of the human hand. This increases the contact with the palm and allows for various riding positions, ensuring maximum safety in all riding positions. Comfort: The shape allows you to easily reach the levers, regardless of your riding position and the size of your hands. The studies conducted on the position of cyclists' hands, showed three different steering positions depending on the course and the steering style. Based on these studies, Campagnolo created the exclusive form of the Ergopower controls that enable you to steer with safety and comfort. In addition, the special insert for large hands increases the distance of the levers by 8%, creating sufficient space for braking and shifting, always ensuring with maximum safety. The geometry of the hoods combined with a material of variable density that is stretchy, hypoallergenic and absorbs vibrations, enables you to stay in the saddle for many hours without hand fatigue. Effective Braking: The lever's Power-Shift shape lets you squeeze the brakes with greater power. It allows you to brake powerfully and promptly even when the hands are gripping high up around the hoods. Buy Campagnolo Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Campagnolo EPS Record 2x11 Speed Front DerailleurFor 2015 there is a new geometry of the mech cage and a NEW software giving different cage strokes. The Campagnolo EPS drivetrain is an organic set of mechanical and electronic components that work together in an integrated way to guarantee maximum performance.In particular, the EPS derailleur interacts with the mechanical crankset and enhances the elevated derailleur speed and precision made possible with X.P.S.S. technology. The 8 special upward zones and 2 downward zones for the chainrings associated to the speed and precision of the new EPS derailleur guarantee top performance.The derailleur is composed of a mechanical structure with dropout and a series of electronic parts. The outer Derailleur Rod held in place by a double-finned pin that passes all the way through to increase rigidity. The System that links the derailleur to the frame is made of aluminium co-pressed with the engineering polymer of the body of the derailleur. This creates optimal solidity and rigidity ensuring that the derailleur maintains a correct position with respect to the frame. The core of the derailleur is composed of an electronic actuator; in turn composed of a gear motor with a built-in resolver that uses Magnetic Hall Sensor technology (as the sensor is not in contact it is not affected by the vibrations generated by the terrain, and is therefore always precise). The gear motor was developed in partnership with a Swiss company that produces electric motors used in missions to Mars. The actuator is also equipped with a "cascade gearbox" which allows movement to be transferred in an exact and rapid manner.Features: Automatic Correction: Compared to the traditional mechanical derailleur that could be adjusted with micro displacements made by acting on the levers manually, the EPS derailleur is equipped with a very sophisticated electronic Automatic Possition Correction system. 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. 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.Buy Campagnolo Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
