The Silver Shifter Adapter is a small part that allows the excellent ratcheting Silver Shifters from Rivendell. to be used with our Thumbies.

This adapter attaches to the square boss found on our Shimano style Thumbies and provides a longer boss to support the inside of the Silver Shifter.

Unfortunately, these cannot be used with SRAM or Campagnolo style Thumbies.
