Cleaned up! One of the hottest circuits for ambitious racers is Shimano's XTR and Dura Ace Di2. The battery is also available in a round version (SM-BTR2), for installation in the seat post. So far, but you need either a seat post with special admission or you have to tinker with construction foam. For round seatpost without special recording Tune is now launching the first clean and simple mounting for the Di2 battery.
Fuels is the little precious helper. With it, you fixed Shimano Di2 battery easily, quickly and safely in round seatpost. It consists of two aluminum plates, two screws and a silicone ring. With about 8 grams of energy weighs a little more than a stick of gum and is almost as easy to use: attach to the battery, slide the battery in the seat post, slightly tighten the screws - finished. The energy carrier contacts the rest only with the silicone ring, that does not scratch. The technique is based on Tunes Steuersatzklemmung GumGum.
