A couple months ago I put Chorus 11 on my bike, been using Campy forever and never had a problem. It worked flawlessly for a while but recently my left shifter on occassion feels real tight when trying to shift up to the big ring, like the cable is too tight however its not because somewhere down the road it will start to shift smoothly again. I have taken the cable out and the shifter seems to work smoothly and when I put the cable back in it shifts flawlessly on the stand and then later starts the same problem. I thought maybe the bar tape was wrapped too tight and was somehow binding it but thats not it and now I am wondering if the cable is somehow sinking into the plastic cable guide on the BB shell but doubt thats it. It seems like a simple fix but I don't know what it is and its pretty frustrating when riding. Any ideas?
