I have a bad right wrist and thumb due to repeated computer use like I am sure many people do. I am looking for gear shifters that would be smooth and easy to use and won't require so much effort from my wrist or thumb. Right now I have rotating friction shifters and they are hard.
Anybody out there with a recommendation for a good brand or an alternative type of shifters?
Best advice would be to quit your job and find something that does not cause these repetitive stress issues that interfere with the joy of cycling.
But seriously, thumb shifters mounted on top of the handlebar can be set up so you can use gross motor movements instead of micro movements to shift... The palm of your hand can push and pull the shifter instead of pushing with your thumb and there is no twisting involved.
For road bars, bar end shifters can be pushed down with the palm and pulled up with almost all your fingers so put very little stress on the thumb and wrist.

If you are using 7 speed rear you can try the Shimano sl-a050. These are mounted near the stem and you can use your palm to shift the gears. the left shifter is friction so will work with double or triple chainrings, while the right is indexed for 7 speeds. The clamps will not fit on those oversized handlebars, so if you are using the 26.0 regular size handlebars, it should be fine.
