Pair of Paul Component Engineering Shimano Thumbies. 22.2mm Clamp for MTB handlebars. Includes nine Speed Shimano Dura Ace Shifters w/ both Index/Friction option for the rear. Purchased for a project bike that didn't turn out. Used for 2-3 rides at most and has sat in my toolbox ever since. Includes all spare parts for the Dura Ace shifter so it can be used as a Bar end shifter as well. Please feel free to message me with questions.
