tune (Germany) – According to tune, “One of the hottest groupsets for ambitious bikers is the Shimano XTR, Ultegra and Dura Ace Di2”. The Di2 battery pack is available in a round version, for assembly in the seatpost, or now also on the fork.

So far it was necessary a seatpost with a special Di2 adaptation. Tune released a new attachment for the Di2 battery, for round seatposts without a special Di2 adaptation.

The small accessory is called Energieträger (energy carrier). The attachment is made up of two alu-plates, two bolts and one silicone ring. It weighs only 8 grams it weights.



How to use it: Pull the “Energieträger” onto the battery, push the battery into the seatpost, tighten the bolts slightly. “The Energieträger touches the seatpost only with the silicone ring, so it does not leave scratches”, stated tune.





The Energieträger is now available as a version for forks, what let’s your battery pack disappear inside the fork.
