How do I change a rear shifter?
Hello. I have a Slx rear shifter and I found an Xtr at a good price so I'd like to upgrade it. I can't find a single video on how to do it. My main concern is if I have to remove the whole cable from the rear derailleur or is it just to simply take the end of it out of the shifter and make a straight swap? If it's the former, I wouldn't be confident doing it myself so I would skip even buying a new one, because of the hassle and extra money for having it installed. I will only get it if I can do it myself.
