Another thing to consider with the Sunrace thumb shifter is that it may not work well with your particular brake lever if you want to use the Riv-preferred orientation. When I installed mine alongside a Shimano Deore T610 lever (which has its clamping screw to the *inside* of the bar), I found that the shift lever interfered with the brake lever's clamp (as shown in the photo below). When the shifter is moved farther forward to clear the clamp, it's then too far forward to operate with my thumb with my hand still on the grip area.

If it doesn't work out -- this, plus the shifting issues mentioned by others -- I’ll switch to a bar-end shifter.
