Aluminium, carbon fibre, high technology & design. The Chorus EPS 11 speed rear derailleur is the product of exactly the same project which spawned the Campagnolo's range topping EPS groupsets. & it has inherited the same class-beating performance.

Features: HIGH TORQUE, HIGH DRIVE RATIO MOTORS: Campagnolo has used the world's best electric motors for this application. These units ensure effective shifting even under strain, deliver the same performance time after time & make extremely fast, precise shifts possible. EXCLUSIVE MULTI-SHIFTING SYSTEM: Lets the rider shift up or down by up to 11 sprockets in a single action! FRONT PLATE & CAGE IN ALUMINIUM: For lightness & superlative stiffness. For fast, precise shifts even under strain. EXCLUSIVE UNLOCK SYSTEM: The manual release system lets the user position the rear derailleur & chain on the desired sprocket in the event of a drivetrain malfunction. The release system also prevents damage to the unit in a fall. UPPER & LOWER BODY IN MONOLITHIC CARBON POWDER TECHNOPOLYMER: For maximum lightness & superlative stiffness. POSITION SENSOR: The Magnetic Hall Sensor Resolver ensures that the rear derailleur always moves the chain into the ideal position for the selected sprocket. 100% WATERPROOF: All the components of the rear derailleur are built to operate in any weather conditions in compliance with the IP67 standard. EXCLUSIVE ULTRA-SHIFT PARALLELOGRAM GEOMETRY: Maximum rigidity, fast actuation & reduced friction. SPECIAL T.I.N. TREATMENT: Specially developed treatment for titanium components to ensure the highest performance & precision for the life of the product. Technology: Unlock System: A manual rear derailleur release system makes it possible to move the rear derailleur manually into the desired position in the event of a system malfunction Waterproof
- IP67: The Campagnolo EPS electronic drivetrain complies with IP67 international standards. Ultra-Shift System: Quickly take the lead & leave your rivals motionless. Specifications: Weight: 225 gr.

A tiny electronic component that performs an extremely important job. It is also used to sets the initial configuration & adjust drivetrain settings during a race, as well as displaying battery level.A vital component for the electronic drivetrain, it may be installed on the handlebar mount or on the brake cables.ANALOGUE-DIGITAL SIGNAL CONVERSION: Transforms the analogue signals received from the controls into the digital signals transmitted to the Power Unit. ZERO SETTING & RIDING SETTING: Used to set the initial configuration of the components & make fine adjustments during a race.RGB LED: Visualises battery charge status.TWO POSSIBLE INTERFACE MOUNTING OPTIONS: The unique design of the interface lets the user choose whether to install it on the brake cable or on the handlebar mount. ...

Features & Benefits External or internal mounting: Specially developed internal casing designed to absorb road vibrations & impact Casing with ultrasonically welded seams Input/output gates DTI™ digital tech intelligence: Adapter for positioning in the seat post Technologies DTI: Digital Tech Intelligence Waterproof
- IP 67EXTERNAL OR INTERNAL MOUNTING: The new cylindrical format allows the battery to be mounted in a variety of positions, all of which confer an aerodynamic dvantage.SPECIALLY DEVELOPED INTERNAL CASING DESIGNED TO ABSORB ROAD VIBRATIONS & IMPACT: For maximum protection of the battery & electronic components on even the worst road surfaces.CASING WITH ULTRASONICALLY WELDED SEAMS: Makes the system 100% waterproof INPUT/OUTPUT GATES: For charging the battery &, when necessary, diagnosing the system & updating the firmware & Eeprom.DTI™ DIGITAL TECH INTELLIGENCE: The digital brain of the EPS™ drivetrain. DTI monitors & checks the battery, transmits & receives signals to & from the interface & controls & monitors the functions of the rear & front derailleur. The unit also checks for system faults, warning the user when necessary via an RGB LED & a buzzer.ADAPTER FOR POSITIONING IN THE SEAT POST: Enables the Power Unit V2 to be fixed rapidly in seat posts with a round or aerodynamic section. Available in two versions (for seat posts 27, 2 & 31.6 mm wide) to permit correct positioning in each seat post.
