I've been setting up my indexing on a stand and all seems fine, however when i'm on the road i seem to have problems changing up gears on the rear. I've got a 105 groupset. If i flick the brake to pop it down gears I have no problems at all. However, if i'm on either of the two largest cogs on the rear then releasing the tension to change up doesnt seem to work well (for either position on the front). The chain will rattle away until i flick it up another gear and then it will jump up and continue to rattle, trying to get into the next gear. Another up-change will pop it in the right gear without issue.
It seems a bit like a sticky cable to me, but its strange that it only happens under load, and only for the lower two of the gears.
Any thoughts? The bike has done 1500 miles approx and is 3 years old. I've only had it for 6 months and put 1200 on it, but i doubt the cables were ever replaced previously. Do you think this is a good place to start? I've lubed the mech's up with GT85 to no avail.
