Why does my bike change gears at random?
When riding my bike I have to constantly keep pressure on the shift trigger to keep my rear gears from switching. If I try to ride it normally without having my hand on the shifter then it will change gear at random, more often so when I pedal harder. This is a bit of a bother and is unpleasant while riding. I have tried to adjust the shifter cables and adjustment screws but to no avail. Any suggestions or thoughts would be of great help :)
