E-TUBE Junction A – Built-in type for frame or handlebar.

Designed for use as a bar-end on drop handlebars or with designated frames, the RS910 junction is a 2-port option for internal E-TUBE wire routing, charging, battery monitoring, and shift mode switching.

The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts.
