Upsidedown thumb shifters?

[tintin40]

How have you found that? Care to share your experiences and opinions? Are you using it on a retro bike, or one of your more modern bikes?

i'd give it 9.5 out of 10. I used two types of wireless and the SRAM is the best with battery life, charging, set up. The only minus for me are the fine tuning when on the move. It can be very fiddly. And the size of modern cassettes. The smallest i've found is the e-13- 9-45. Which has just come out . Before that i was stuck with a dinner plate 9-50. I use these on my retro-modern 26er , V brakes, rigid. single chain ring, 12 speed. My take on what a mtb should be now. My retro bike is on my turbo trainer.
