Campagnolo offers this updated cylinder-style EPS Power Unit (battery and digital brain) for internal mounting with Super Record and Record EPS drivetrains.. At just 16.6mm in diameter and 232mm long, the unit will fit inside most seatposts and internal frame mounting systems using either downtube or seattube bottle cage bosses (with available mount and tool). Campagnolo supplies the simpler adapter system, featuring an included elastic wrap and shim system that works for some tube shapes and sizes. This version of the internal power unit maintains all of the previous characteristics and technologies that derive from the V2 version, such as a vibration absorbing outer material, ultrasonic seals providing a waterproof construction and industry leading autonomy and house them all in a slimmer, more versatile package with both ANT+ and Bluetooth Smart communication options.

The EPS V3 Power Unit houses the battery and the Digital Tech Intelligence unit which transmits, receives and processes data thousands of times a second. This electronic brain which instantaneously synchronizes 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 unmatched levels of performance and control. The system also monitors the entire drivetrain and each of its components, continuously checking battery level and functionality, and checking that the rear and front derailleurs are working correctly at all times.

With an IP67 water protection rating and a housing that carries and protects the crucial internals, the EPS V3 Power Unit for Super Record/Record weighs only 106 grams. It is fully compatible with current EPS wiring fitments, and automatically diagnoses faults and problems with an on-board diagnostic system. Campagnolo offers the My Campy app to maximize the data and information from the the D.T.I. unit and can help you make adjustments based on how you actually use the system. The system is smart, reliable, and easy to use. A final advantage of the new power unit is the 16.6mm comes within 4/10 of a millimeter of Shimano's unit, so many of the seatpost and frame mounts that work with Shimano may also work with EPS V3.
