      I run these flipped under the bar with both shifters set in friction mode. They are well made, beautifully machined, and function flawlessly! You can't go wrong with anything from Paul Components!

      Comments about Paul Components Shimano MTN Thumbies:

      These thumbies are really great. I used them to put 9sp DuraAce bar ends on my flat bar touring bike. The bike is a double ring with a 7sp DuraAce front der. that I had in the closet, and an XT 9sp rear. The shifting is fantastic. A few minor issues when going this route compared to using normal mt bike shifters. First, the bolt that comes with the thumbies does not cover the shifter end like the Shimano bolt does. You can't use the Shimano bolt because it's not long enough. It's mainly an aesthetic thing, but could also be an issue if you ride in lots of rain. Might want to think about covering up the bolt heads with tape or silicon. Second, with the shifters on top of the bar, they get a little smashed if you need to flip the bike up side down to change a tire or play with the shifting. Not a problem on the home bike stand, but I tend to do a lot of bike flipping when on a long tour. Just need to be careful and find something softer than pavement. Overall, coming from a mt bike background, I found these easy to get used to and will likely keep them on my touring bikes for the long haul.

        I got rid of my indexing shifters. I ride rough terrain and bunnyhop alot so this won't wear our the bushings because of the friction mechanism.

        I recently completed my bike build using the ergonomic Titec H-Bar and utilized the Thumbies from Paul Components. They have been a great addition and allow me to shift gears with no problems using the H-Bar.
