This is for those of us that do not want to use any straps, ties or tape to hold on their Di2 Junction 'A' box. It is a combination of a 5 mm headset spacer and the slide on clip. This differs from other clips as it is angled 17° so the junction is mounted parallel to the ground. If you are willing to give up 5 mm of saddle to handlebar drop, this is for you. Designed to fit 1.125" (28.6 mm) fork steerer tubes.
