I recently had to replace the shifters on my bike. The replacement was easy enough, but now when I shift the derailleur either jumps too far or too short. I've tried using the adjustment screws on the derailleurs but I feel like I am doing something wrong. I think I'm just going to disconnect everything and I was looking for a guide to do this properly.
Also I don't have a rack to hang the bike while I work so I will be working on the bike upsidedown.
Edit: Yes I have the right shifters. They are the same exact model as the ones i replaced.
