Shimano SM-EW90-B Junction Box For Dura-Ace / Ultegra Di2

Shimano Junction SM-EW90-B – Especially for time trial handlebars
The SM-EW90-B junction box by Shimano is a variant of the junction A connection point for the cockpit area. It has been specially designed for time trial handlebars and is therefore aimed primarily at riders of Dura-Ace Di2 (from 9070, before R9250) and Ultegra Di2 (from 6870, before R8150) groupsets. This junction has five E-Tube connections, one charging connection and is mounted externally under the stem. Its software, which can be kept up to date via the E-Tube platform, determines data such as the current gear position or the battery charge level.
