Pinarello Seatpost Internal Battery Mount for Di2 - $89.95

The reasons for running Shimano's new Dura-Ace 9070 Internal Seatpost Battery seem to keep multiplying. For one, this setup shaves a substantial amount weight off of the group set, lowering it to a weight that's actually lower than the 9000 mechanical group. However, as we're sure that you've noticed, accommodating seatposts have been slow to come to market. Luckily, though, Pinarello has been forward-thinking enough to already have designed the Seatpost Internal Battery Mount for Di2. So, if you're looking to maximize your 9070 setup by utilizing the SM-BTR2 Internal Battery, this is your fast track to weight savings and element protection. The Pinarello Seatpost Internal Battery Mount for Di2 is available in the color Black and in one size. Please note that this mount is only compatible with the Pinarello Dogma 60.1, Dogma 2, and Dogma 65.1 seatposts. Additionally, it is only designed for use with the Shimano Dura-Ace 9070 SM-BTR2 Internal Battery. - $89.95
