Shimano BT-DN110-1 E-Tube Di2

Integrated battery of the latest generation, which is sunk in the seat post or the steerer tube. With the internally laid cable results in a tidy look of the road bike. The integration of the battery in the frame also reduces the number of attachments that are in the wind. For the top groups Dura Ace Di2, XTR Di2 and the upper middle class Ultegra Di2 and XT Di2 Shimano uses only the best battery technology! Therefore, the battery consists of two high-quality lithium-ion cells. These cells offer a high capacity and thus keep about 2000 km with numerous switching operations. The lithium-ion technology allows the battery to be used in a wide temperature range of -20 to 60 ° C and therefore to use in every season. Bluetooth technology allows drivers and mechanics to communicate wirelessly with the Di2 system by connecting the wireless unit in the SC-MT800 or the EW-WU101 to a tablet or smartphone.
