Paul Thumbies are the original upright handlebar shifter mount. They easily transform bar end (aka barcon) shifters into thumb shifters. Thumbies bring back the thumb shifting of old, but this time around make shifting more precise and smoother than ever before.
Thumbies have a hinged clamp for an easy installation.

Comments about Paul Components Paul Thumbies For 26.0 Road Bar:
There are two big negatives here: ONE, pretty pricey for what is effectively just a mounting system for non-included shifters. TWO, it is going to be unusual that you will effectively be able to use both of these thumbie mounts on one bike without doing something wonky. (If you are using 26.0, presumably you have a drop bar. The most natural mounting position is just to the right and left of the stem where the drop bar clamps. But the cables leave the thumbie at the same location on both the front and rear clamp, so they run directly into each other. You would need to (1) take up a substantial amount of the top of your drop bar to avoid cable routing conflict, absurd (2) offset the angle of the thumbies, which is wonky and unergonomic, OR (3) only use one and stick the other bar-end shifter in the bar end.) (3) is a good solution, but now problem ONE is really a bigger problem, because you are effectively paying full-freight for one usable mount.....and maybe hoping to recoup a little by reselling the unused rear mount.
That said, these are *very* nicely manufactured, durable, and easy to install. They allow me a set-up which I love on my touring/commuting bike. On drop-bars, I've got a mirror in the left bar-end, the rear shifter in the right bar-end, and the front shifter mounted up-top for use by my left thumb. Gives me a non-indexed front shifter for a wider gearing range and allows me to use the greater pull of a V-brake type brake lever. So I'm in love with that.....and have literally put thousands of miles on the shifter and thumbie without anything remotely approaching a problem.
