Rivendell Thumbie Mount for Silver Shifters

Installation note: this is a small part and doesn't require much force to clamp down. Overtightening the thumbie mount may crack it. Tighten just enough to keep it in place, no more.

Individually sold, left or right thumb shifter mounts for moving downtube style shifters up to a more comfy and accessible spot. These'll fit 22.2 or 26.0 handlebar diameters, so they can either be on the grip area of a standard straight or swept-back bar, or on the clamp area of a drop bar.

Their unique design allows a rotation of the cable exit point with 16 possible positions. This allows you to fine tune where your thumb shifter will be positioned for a perfect fit.

Compatible with Dia-Compe and Rivendell friction downtube shifters, and some others. Not Microshift compatible.
