Mounting the Thumb Controller

0:36 - 0:46 min.

The optimal position for the thumb controller is between the grips and the gear shifter. It can be attached left or right on the handlebar. Ensure that the bell button faces downwards.

For most handlebar diameters, use the normal thumb controller adapter pre-fixed to the controller:

  1. Remove the bracket from the Thumb Controller by fully disassembling the long screw

  2. Position the brackets between handlebar and shifter/brake

  3. Mount the thumb controller (2.5mm Allen key)


Position the Brackets

Mount the Thumb Controller


For thicker handlebars (e.g. taped drop bars) , use the alternative thumb controller adapter:

  1. Remove the bracket from the Thumb Controller by fully disassembling the long screw

  2. Attach the alternative adapter to the controller using the same long screw

  3. Fix the thumb controller to the handlebar by using both cable ties
