**Campagnolo Interface DTI EPS V2** The EPS electronic drivetrain functions with digital signals. Because of this, the electronic drivetrain needs an interface, which performs the vital function of transforming the analogue signal received from the Ergopower controls into a digital signal, which is then transmitted to the Power Unit. The interface also has important functions such as: * displaying the battery charge status * processing information coming from the rear and front derailleur through the EPS Power Unit * registering the initial set-up and allowing micro adjustments of the rear and front derailleur even while riding * serves as a diagnostic mechanism displaying colour coded signals for any eventual problem with the EPS drivetrain Zero Setting / Ride Setting: The interface processes the data received during the initial setup of the front and rear derailleurs (Zero Setting) and also during smaller adjustments (Ride Setting). These smaller fine-tuning adjustments can be carried out while in the saddle as well. The DTI interface transmits and receives signals to and from the Power Unit thousands of times every second, processing them accordingly to ensure that the drivetrain functions correctly in all situations. The special design of the interface lets the user choose between two different installation solutions: on the brake cable or on the handlebar mount. The RGB LED lets the rider view the state of charge of the battery at any time. Weight: 24 g
