My right Shimano shifter is now loose and clicking it doesn't do anything to the rear derailleur. I've checked the derailleur and it still works fine. How can I fix the shifter?
Edit: It's a road bike cable shifter; it has the brakes with it as well so it's a brifter (?). I have potentially found the problem. Something in the cable seems to have snapped as the cable has come out of the shifter. Any way to fix that?
Edit 2: I realised that someone shared a link on how to replace the cable in the comments so this question has been answered. Thank you everyone.
