Campagnolo Chorus 12 Speed Rear Derailleur
  • £149.99

New 12x Chorus rear derailleur for use with the disc or rim brake groupsets.The new 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 new optimized 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 makes this rear derailleur suitable for all cassettes as the distance stays optimum on each individual sprocket, regardless of the cassette selected. Technologies: 3D Embrace Technology: 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., . Key Features:Constant precision: On rough roads, the spring positioned between the upper body and the pivot absorbs the vibrations, ensuring the chain always rests properly on the sprockets.,The pulley wheels on the 12-tooth derailleur cage allow the chain to move more smoothly.,The initial position of the rear derailleur can be adjusted to suit any cassette.,Easy wheel replacement: The rear derailleur is positioned further back, making it easier to slide the wheel out and replace it.,Weight: 240g.

Campagnolo Chorus 2x11 Speed S2 Front DerailleurWarning: Not compatible with 2014 Groupsets The Chorus front derailleur excels in shifting performance and is comparable to its siblings Record and Super Record. This mech operation is fast, responsive, and precise with the chain moving between the rings with no hesitations.With the new Super Record, Record, and Chorus groupsets, shifting is extremely easy thanks to the long front plate of the front mech body, meaning greater leverage and therefore truly reduced movement when shifting. Shifting precision is achieved thanks to the design of the new narrower cages. The semi-inner cage, in aluminium, has features that improve shifting speed.New Cage In Light Molded Alloy: Enabling crisp, rapid, precise and above all silent shifting thanks to the plate on the tip of the outer semi-cage.Features:Special inner cage designCSD (Chain Security Device), optional add-onDerailleur cable deviator insertDerailleur clip clamp, optional add-onWeight: 76 gramsBuy Campagnolo Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Campagnolo Chorus Eps 11 Speed Rear Derailleur Rear Derailleurs
  • £266.99
  • RRP £396.99
  • Saving you £33

The Campagnolo Chorus EPS groupset takes a great deal of its DNA from its mechanical counterpart as it represents a more accessible version of Campagnolo performance, quality and attention to detail but delivers it in the laser-like precision package of an EPS drivetrain. The shifting performance of the Chorus EPS groupset is exactly the same as its lighter weight siblings, Record and Super Record, making for a transmission fit for professional racing. Shifting even under heavy load is no problem for the Chorus EPS transmission and mud, grime and debris have met their match against such powerful motors. 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 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. Waterproof 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.

  • Saving you £39

The Campagnolo Chorus EPS groupset takes a great deal of its DNA from its mechanical counterpart as it represents a more accessible version of Campagnolo performance, quality and attention to detail but delivers it in the laser-like precision package of an EPS drivetrain. It's extremely powerful motors are capable of producing levels of torque without rival in electronic shifting which guarantee precise and effective shifting no matter the conditions or circumstances. Shifting even under heavy load is no problem for the Chorus EPS transmission and mud, grime and debris have met their match against such powerful motors. With an IP67 waterproof rating on the entire system rain gear is only necessary for the cyclist, not his groupset. The dérailleur is composed of a mechanical structure with dropout and a series of electronic parts. The outer Dérailleur Rod held in place by a double-finned pin that passes all the way through to increase rigidity. The System that links the dérailleur to the frame is made of aluminium co-pressed with the engineering polymer of the body of the dérailleur. This creates optimal solidity and rigidity ensuring that the dérailleur maintains a correct position with respect to the frame. The core of the dérailleur 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. AUTOMATIC CORRECTION: Compared to the traditional mechanical derailleur that could be adjusted with micro displacements made by acting on the levers manually, the EPS dérailleur is equipped with a very sophisticated electronic AUTOMATIC POSITION 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. WATERPROOF: 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.
