Thumb shifter mounts allow you to mount down tube and bar end shifters on your handlebars. Thumbies put your shifter within easy reach while avoiding the complexity of brifters. This allows for a comfortable setup for city bikes, MTBs, porteurs. They can even be used on even drop bars.
They fit standard road, MTB, and city handlebars (22.2mm and 23.8mm grip area). VO shifter mounts feature a hinged mount so you do not need to remove your bar tape or grips or brake levers to install them.
They fit Dia-Compe Downtube Shifters, Dia-Compe Bar End Shifters, Shimano 9/8 speed Bar End shifters, Silver Downtube/Bar End Shifters, and many others.
Sold as a pair. Shifters not included.
