A tiny electronic component that performs an extremely important job.

The interface transforms the analogue signals received from the controls into the digital signals transmitted to the EPS™ Power Unit™.

But that's not all it does. It is also used to sets the initial configuration and 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" AND "RIDING SETTING": used to set the initial configuration of the components and 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.
