How to place the Di2 distributor elegantly under the stem

Shimano's Di2 shifters are bursting with high-tech - but the simple rubber band that attaches the distributor to the stem is far inferior to the appearance of the electric components. Swiss bike manufacturer Koba has now come up with a clever part that parks the Di2 distributor in the right place.

Away with rubber bands or cable ties: that's the motto for the Di2 junction holder from Koba. The mount for the Shimano Di2 Junction Box - also known as the SM-EW90 distributor - disappears elegantly under the stem. This also makes room for a GPS, smartphone or bike computer.

The distributor holder can be mounted on the 1 1/8-inch steerer tube like a spacer and measures 6 millimetres in height. The weight is negligible, the simple part weighs a modest seven grams. The retail price that Koba charges for the Di2 mount is also modest: the simple mount is available for the recommended retail price of CHF 5.
