Thumb Shifter Mounts


Sold Out

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.

  • Compatible with any standard road, mtb, and city handlebars (22.2 and 23.8mm grip area)
  • Hinged design so you don't need to remove any components or accessories for installation
  • Integrated barrel adjustor to dial in cable tension on the fly
  • They fit Dia-Compe Downtube ShiftersDia-Compe Bar End Shifters, Shimano 10/9/8 speed Bar End shifters in addition to a ton of vintage downtube and bar-end shifters

Sold as a pair. Shifters not included.

Note: Not compatible with Microshift shifters (the shifter is too tall) or Dia-Compe 11s road/10s dynasys shifters.

Great quality, no instructions

The shifters are very well made. It would be nice if there were instructions included, and possibly another color to choose from. But, all in all they work great and allowed me to use my vintage downtube shifters on the handlebar. Also, the shims that were included fit perfectly. Great product,

Awesome to have these, helps bigtime with old road bike conversions. Look very clean also!! Keep making cool products like these

Devin Bishop
Work great

Mounted my 9 speed bar ends onto a Jones Bar with these.

Thumb Shifter Mounts

I really like these. My only complaint is that I wish the shifters mounted slightly higher to give more clearance from the grips
