Shimano BT-DN110-A-1 DI2

Integrated battery of the latest generation, which is sunk in the seat post or the steerer tube. The integration of the battery in the frame also reduces the number of attachments that are in the wind. To charge the battery, this can remain in the bike with a SM-BCR2 charger. The internal battery needs 1.5 hours of charging and offers a high capacity of about 1000 km depending on the circumstances and 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.
