Shimano Gears won't shift Basically when pushing the button to shift gear I can only get one speed up and one speed down. I tried adjusting derailer and the tightness on cables but it makes no difference.

Figured I'd make a video to explain it better
here you go.


                
            

thanks and  ask questions if needed
Can't really tell much by your video. We see you clicking up &amp; clicking down, but you don't appear to be turning the cranks. The gears will not shift unless the drive train is in motion.
