Ok, I took my Bianchi in to get the "sloppy shifting" looked at. I have Ultegra components - so Im thinking the performance should be better than it is right now. First thing I did a month ago was take the chain off and cleaned it - the pin did come out completely - could this be the problem? Anyways, I lubed the chain with white lightening. The shifting still had a sloppy feel to it. Going from one gear to the next, it will make a clunk and grab on - not very smooth, almost like I tossing the chain onto the gears and it grabs that way. Sometimes attempting to shift to the big cog in back - going up a climb, I shift and it comes back into the gear I had it in - I really have to hold the shifter to get it to stick. So the bike shop adjusted (apparently) the front and back derailers - but its still the same this week. Do I need to look at lubing the derailer hinge points? Is the chain bad? Any ideas?
