The professional way to mount your battery.
You learn a few tricks when the top team you build equipment for chooses to run electronic drivetrains. This has been the case for a while now at Pinarello, as its partnership with Team Sky was instrumental in the development of the new flagship Dogma F8, complete with internal cable routing that keeps everything tidy and, well, professional.
This carries over into the power system, too, as the F8's Air8 seatpost has been designed to seamlessly house Shimano's SM-BTR2 Internal Battery. The mounting hardware that makes this possible is simply called the F8 Di2 Seatpost Mount, which provides a secure hold on the battery, in addition to keeping it tucked away and out of the elements.
The Pinarello F8 Di2 Seatpost Mount is available in the color Black and in one size. Please note that this mount is only compatible with the Pinarello Dogma F8. Additionally, it is only designed for use with the Shimano SM-BTR2 Internal Battery.
