Thumb Shifter Mounts

Don’t throw out those vintage downtube shifters – they’re the perfect match for city bikes, tourers, and porteurs! They’re lightweight, simple, inexpensive, and are compatible with almost any front and rear derailleur. Although, they can be a pain to reach for in traffic.

The VO Thumb Shifter Mounts allow you to mount downtube and bar-end shifters on your handlebars. These thumbies put your shifter within easy reach while avoiding the complexity of brifters. They can even be used on drop bars.
