The Campagnolo EPS V3 battery seatpost adapter is designed to help accommodate your Campagnolo EPS DTI V3 Power Unit.
The Power Unit was originally modified to be mounted internally both to protect it from the elements as well as to confer an aerodynamic advantage to the overall build. With the advent of increasingly aerodynamic frames and with them even slimmer tube forms Campagnolo has produced an even more advanced version of its power unit - the V3.
This new version of the internal power unit maintains all of the previous characteristics and technologies in a slimmer, more versatile package.
This new structure opens up the possibilities for internal mounting not only in the most aerodynamic framesets with very slim tube designs but also gives a greater deal of flexibility with regards to placement within the frameset. Thanks to this new slim structure the EPS advantage is now available for all frames, no matter which make or model you choose.
The reduced diameter (16,6 mm) allows the V3 Power Unit to be mounted within the seatpost, by using one of the two available adapters (for ø 27,2 and ø 31,6 mm), thus reducing assembly time.
