CHORUS EPS V2 POWER UNIT

The new design allows for INTERNAL mounting which not only offers the obvious aerodynamic benefits associated with hiding a component inside the frame but also keeps the unit protected from the elements and impact.

The new EPS™ V2 Power Unit is an improvement with regards to aerodynamics, versatility, durability and protection but also plays a pivotal role in an aspect that is not to be overlooked; aesthetics.

The new EPS™ V2 Power Unit gives the cyclist the possibility to use the most advanced groupset while maintaining sleekest look to his or her ride.

The brain of the system.

The EPS™ Power Unit™ is much more than just a battery. Its housing contains all the electronics of the EPS™ drivetrain, the system memory input/output gates and the battery charger plug.

This design choice benefits both the reliability and the performance of the system, which is also upgradeable.

Features 

Enclosed and protected in the Power Unit™ and interface, "Digital Tech Intelligence" transmits, receives and processes data thousands of times a second.

An electronic brain which instantaneously synchronises all the functions requested by the rider. With just a simple click of the controls, D.T.I™ transmits the corresponding signal instantly, accurately and reliably to the rear or front derailleur, for levels of performance and control feel never experienced before with a conventional drivetrain.

But as well as all this, the D.T.I. system also monitors the entire drivetrain and each of its components, continuously checking battery level and functionality, and checking that the rear and front derailleur are working correctly.

  • Weight: 130 grams
EXTERNAL 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 AND IMPACT
For maximum protection of the battery and 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 and, when necessary, diagnosing the system and updating the firmware and Eeprom.

DTI DIGITAL TECH INTELLIGENCE
The digital brain of the EPS™ drivetrain. DTI monitors and checks the battery, transmits and receives signals to and from the interface and controls and monitors the functions of the rear and front derailleur. The unit also checks for system faults, warning the user when necessary via an RGB LED and 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 and 31.6 mm wide) to permit correct positioning in each seat post.
