DI2 seatposts coming up, PRO R&D is working on the last details!
First DI2-ready seatpost samples arrived @ PRO R&D. After a double check with the 2D drawings some small adjustments to be done, but the system works already very nice! Only 6 to 8 grams additional weight to the seatpost, but the overall weight reduction of internal vs external is about 20 grams. Needles to say that hiding the battery gives a nice and cleaner appearance.
