Two types of thumbie mounts for most modern downtube shifters
Out of stock

These simple adapters let you use downtube shifters on your handlebars, like classic thumbies. Use them with indexed or friction shifters.

  • Microshift model fits Microshift levers
  • Shimano model fits Shimano, as well Dia-Compe, Rivendell, and any other shifter using Shimano bar-end or downtube-style mounting
  • Mounts to bars with 24.0mm or 22.2mm grip area
  • Lightweight CNC-machined aluminum
  • Probably won't fit old French or Campy levers, sorry

Bought these to add thumb shifters to drop bars. Unfortunately they are not designed to fit 11 or 12 speed Micoshift shifters, not enough room around the barrel of the shifter so if you want to use them for a wide range mullet drive you'll either have to try some judicious filing or wait for the Paul Thumbies to be back in stock.
