Hi all, Appreciate for any advise re front barrel adjustors: After watching some YouTube I finally went ahead lowered the front derailleur to: (a) Close the big gap between the cage/ chainring; (b) minimize the chain rubbing issue. During this process I found out that the front barrel adjustor won't work at all. It can't be turned at all. I tried totally loosen the cable, and re- tighten everything,... adjust the cable housing.... Nothing works ..... My shifting is fine right for now, so my question is : (1) Should I bother to go to my LBS to ask them to fix this issue? Unless this is something that is very critical down the road, I don't really want to bother to go back to my LBS. (2) I'm just very curious how would one fix it if it needs to be done in the end? Can the barrel be removed without damaging the frame??... I mean I don't see any mechanism there that would allow one to remove it and replace a new one... like...... the v-brake.... or other parts of the bike .... (if you understand what I'm talking about? ) Thanks a lot in advance! p's. My bike is 2013 Trek Lexa SLX C
