If a gear shift button hasn't been tightened with the appropriate torque of 1.1Nm, it can unscrew and get lost.

We deliver either:
- one single spare gear shift button including set screw M3
- one set of two buttons with tools for tightening

For the professional: please use the 1.1Nm torque screw driver. This tool gives a 100% reliability against lost of buttons.
We grant a lifetime warranty against lost of buttons, if they have been installed with this tool!
