Energieträger - 8 gram
One of the hottest groupsets for ambitious bikers is the Shimano XTR and Dura Ace Di2. The battery pack is also available in a round version, for assembly in the seatpost. So far one needed a seatpost with a special Di2 adaptation or crafting with expanding foam was necessary. Tune releases a clean and simple attachment for the Di2 battery, for round seatposts without a special Di2 adaptation.
Energieträger (energy carrier) is called the small super-domestique. With it, one fixes the Shimano Di2 battery easy, fast and secure in round seatposts. The part 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 “Energieträger” is now available as a version for forks, what lets your battery pack disappear savely inside your fork.
