System Information Display - Junction A

SC-M9050 - System Information Display - Junction A image

The SC-M9050 System Information Display shows you what gear you're in, has a battery level indicator, charging port, synchronized shift mode display and also doubles as a Junction A - it has 3 e-Tube ports for you to connect components to it.

It supports both 31.8mm and 35mm diameter handlebars.

If you're thinking of using this display on your road bike to replace your Junction A (SM-EW90 / EW-RS910) you can - however.. this component does not feature wireless connectivity and the newer SC-MT800 and SC-M9051 are much better options.

Newer and better alternatives

The SC-M9050 is the older version of Shimano's information display. The current SC-MT800 and SC-M9051 displays are your go-to display if you're buying one now. On top of the functionality of the SC-M9050, these two units also add wireless (BluetoothLE / ANT) connectivity.

These newer displays do require a modern battery (BT-DN110) or battery mount (BM-DN100). They will not work with the older batteries.
