I got a new Giant propel Pro with an Ultegra groupset back in April, but I am having a lot of trouble getting the gears set up correctly. It is now at a point where I feel they need adjusting after every use or clean, and the worst thing is that I have had to sacrifice the option of using the big ring at the back to let the other gears run smoothly. I know I shouldn't use this gear and the big ring, but it is nice to have the option in the middle of a race.
I have replaced the new cable to try and improve things, but it didn't seem to do much.
I have heard something similar had happened to someone I know, and they were unable to find a fix, but any advice or solutions would be great.
