The small super-domestique is called Energieträger (energy carrier). With it one fixes the Shimano Di2 battery easy, fast and secure in round seatposts. The attachment is made up of two alu-plates, two bolts and one silicone ring. With only 8 grams it weights about as much as a chewing gum and is nearly as easy to use: Pull the "Energieträger" onto the battery, push the battery into the seatpost, tighten the bolts slightly - done.
The "Energieträger" touches the seatpost only with the silicone ring, so it does not leaves scratches. The technique is based on the head tube clamping GumGum.
If use with other seatposts please check the inner diameter.
Not suitable for seatposts with inner oval shape.
Seatpost and battery not included.
