Campagnolo Record EPS 11sp Rear DerailleurAs with the mechanical parts, the rear derailleur represents the pride and joy of the EPS project and encompasses a series of technologies and innovations that allow shifting speed to be optimised and guarantee unprecedented precision, even in the case of multiple shifting with 11 sprockets at a time.The EPS rear derailleur is comprised mainly of a mechanical structure, derived from the mechanical gear and composed of a derailleur rod/parallelogram/derailleur cage, of a worm screw enabled by an electronic actuator. As with the derailleur, the electronic rear derailleur actuator is composed of a gear motor and a sensor, the built-in resolver, that reads its movements. The geometry of the parallelogram has been made more rigid and optimised to promote interaction with the electronic parts. The lower and upper bodies, the parallelogram and the carbon derailleur cage are moved by a screw system and lead worm screw (not a spring screw) which, in turn, is enabled by the electronic actuator that communicates with the DTI. The built-in resolver inside the actuator is capable of reading the movements of the rear derailleur at any time and optimising its position by communicating with the DTI (Digital Tech Intelligence). The rear derailleur is also equipped with a play recovery system using a helicoidal spring that optimises stability and precision and keeps operation and performance constant over time, even after many kms have been covered. As with the mechanical rear derailleur, it is possible to optimise its position with respect to the frame and chain by acting on two adjusting screws: the screw that adjusts the mechanical end stop and the screw that adjusts the distance between the upper pulley and sprockets. By using these screws it is possible to optimise the installation of the rear derailleur and increase the precision of its operation.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.Ride Back Home: The uncoupling mechanism of the rear derailleur is useful if the battery runs out "on the road", allowing you to manually "uncouple" the rear derailleur to position it on which ever sprocket you require.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 their internet site www.campagnolo.com.Buy Campagnolo Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Campagnolo Chorus 12 Speed Rear DerailleurEngineered for toughness and reliability, this 12 speed road bike rear derailleur features a hard-wearing aluminium build. Campagnolo has also developed this model for constant precision, even on rough roads, by positioning the spring between the upper body and the pivot to absorb vibrations and ensure the chain always rests properly on the sprockets. Another highlight is the pulley wheels on the 12 tooth derailleur cage allow your chain to move more smoothly for efficient shifting. The initial position of the rear derailleur can be adjusted to suit any cassette plus it offers easy wheel replacement by positioning the rear derailleur further back, making it easier to slide the wheel out and replace it.12 Speed Rear Mech with 3D Embrace TechnologyThe updated Chorus rear derailleur benefits from the same technology and design of top-end Campagnolo products, incorporating the sophistication and performances of the 12 speed Super Record and Record. With just a few changes in the materials used for its construction, like the external plate and derailleur cage in aluminium, the Chorus version produces exactly the same performance as the two more expensive groupsets with the addition of just a few extra grams. Chorus brings with it the same technology as the next level up, like the optimised trajectory on bigger cassettes and fantastic 3D Embrace technology. The latest evolution in Embrace technology not only keeps the rear derailleur vertically aligned in the perfect position for each sprocket, it now makes the upper pulley wheel advance perfectly in the direction the bike is advancing. 3D Embrace technology and 12 teeth pulley wheels make this rear derailleur suitable for all cassettes as the distance stays optimum on each individual sprocket, regardless of the cassette selected.Features: Material: Aluminium Use: Road Cage Size: Medium Speed: 12 speed Constant precision 3D Embrace Technology Optimised Trajectory Optimised Return Spring Easy wheel replacement Weight: 240gTechnologies: 3D Embrace Technology: The movement of the rear derailleur is designed to make the chain embrace more teeth per sprocket to guarantee maximum traction. Optimised Trajectory: Movement of the rear derailleur means that the upper pulley wheel on the cage is always constantly close to the sprocket in use. 12 Tooth Pulley Wheels: Perfect for cassettes that have a wide range of teeth. Optimised Return Spring: This guarantees constant chain tension regardless of road vibration. Suitable for use with the disc or rim brake groupsets.Manufacturer's Part Number: CPB115 Black Medium CageBuy Campagnolo Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
