Mounting the Rohloff E-14 Switch Unit

The Rohloff E-14 Switch Unit is used to send commands to the Rohloff E-14 Shifter Unit.

A guide to mounting this switch can be found below:

The Switch Unit is designed for mounting to standard, 7/8" (22 - 22.3mm) diameter bicycle handlebars.

We recommend mounting the Rohloff E-14 Switch Unit to the right-hand side of the handlebar between the grip and the brake lever. The Switch Unit should be angled so that the '+' and '-' buttons are ergonomically positioned for the thumb of the rider.

Note: The E-14 Switch Unit can also be mounted on the left-hand side of the handlebar if preferred.

In order to mount the Rohloff E-14 Switch Unit, remove from the packaging and unscrew/remove the Switch Unit, rear clamp section. Remove both 3mm Allen-head screws by rotating them in a counter-clockwise direction.

Now place the Switch Unit on a free area of the handlebar ready to secure in position.

Place the rear, clamp section of the Switch Unit around the handlebar and secure insert both 3mm Allen-head screws. Thread the screws evenly into the Switch Unit, in a clockwise direction, so that the gap between front and rear Switch Unit sections is identical. Finally secure the screws with a maximum tightening torque of 1Nm.

The Switch Unit should now be tightly mounted to the handlebar.


It must be possible to place the clamp section of the Switch Unit around the handlebar without the need to apply force. Pay close attantion to the direction of the clamp, to avoid pinching the exiting cable!

The blue, 4-Pol connector of the E-14 Switch Unit cable, must be connected to the blue, 4-Pol connector of the Rohloff E-14 DC/DC-CAN Converter cable.


Refer to Cables and Connectors

Cable routing on handlebar / frame

The cable connector should be anchored/attached to the handlebar in such a way that it cannot be kinked, twisted or broken during normal cycling use or squashed via the use of other components. (e.g. use of brake levers, attachment of handlebar bags etc.). Extra caution is required to ensure internally routed cables are hindered from abrasion.

Routing cables and/or anchoring the cable connectors to the handlebar must not hinder the function of any other component located on the handlebar or frame.
