I need to adjust the h-limit screw since there’s chain rub when on the big ring and smallest cog. I can do this without having to do the whole fd tune up, right? L-limit is set ok and the shifting is ok as well. Bike mechanic didn’t set the h-limit properly last time i had it tuned up. I now do the bike tinkering on my own. While i’m confident doing the rd tune up, i find the fd tune up a bit tricky, especially setting the cable tension correct. Cable tension is currently set ok, shifting is fine, so i don’t want to tinker with it unless necessary.
