105 is good stuff. I have over 20,000 miles on my shifters and front deraileur with no problmes at all and still shifting perfectly.
Is the bike new? The cables sometimes need several adjustments for a period of 60 day s or so. I 've had some adjust once, and other stuff needed 4 or 5 adjustments (Ultegra). Depends on the new cables themselves.
If it's old, like the other guy said, may need new cables. Sometimes they fray in the shifters where not visible.
I had a shop guy tell my bud that his Ultegra can't be adjusted any better than what it was. He told my bud "that's why we sell Dura Ace"
....It took me aobut one minute to adjust it on the side of the road. He was very happy after that!
