I have the dura ace 7900 front shifter and derailleur and after my shifting cables have been replaced I have noticed the following.
I cannot trim anymore. The chain jumps onto the big chainring with only 1 click. Previously I could shift into the big ring with 2 clicks.
I cannot shift into the small ring. Well I can but the chain stays on the big ring while I pedal. Only after I turn the cranks for a while the chain drops into the small ring.
I can rule out worn cables and housing since those were replaced right as this problem came up.
I have tried adjusting the cable tension with the barrel adjuster but that yielded no results.
Any ideas ?
