Thanks to the robust switch, the driver retains control of the drive at all times. The buttons are smooth-running with a clear pressure point and thus provide clear feedback to the driver while driving, without the need for a distracting look at the display. The upper of the three buttons changes the display as required. The two lower buttons are used to increase or decrease drive assistance. With this intuitive operation, every bike tour becomes child's play. - Purpose: derailleur gears - Details: - Incl.
