  • Tidy! 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 technique is based on the head tube clamping GumGum. The Energieträger costs 19,90 Euro and is available for the diameters 27,2 millimetre,30,9 millimetre and 31,6 millimetre. Typical Tune it weights only 8 respectively 10 grams.
