i have been using shimano ultegra all my racing career to date (rear mech, front mech, cranks, bottom bracket, brake calipers, shifters) and never had any problems with it until the day i snapped my chain on a climb about a couple of months ago..i then took off the old cassette and placed a brand new one on(shimano ultegra) with a brand new chain (kmc) and the gears were alright for about two weeks before i started having a few indexing problems and noises here and there before the indexing was so bad i got my mate a bike mechanic to fix the gears but i wasn't completely happy as im a fan of smooth shifting and silent running which the shifting was ok and there was some noises here and there and again i had another indexing problem in a few weeks which i left my bike in to be serviced and replace the gear cable in a well known bike shop and when i took the bike out i had problems with the gears still not shifting 100% and not silent 100% as you could hear irritating noises when the chain was in certain sprockets on the cassette..so i then bought a brand new rear mech and front mech and left it in to another well known bike shop to put on the bike, replace the gear cable again, service the bike again and ensure everything sweet and make sure the shifting perfect or 90% at least..so today i took the bike out and the shifting is good but...theres loads of different levels of noises coming that what ever selection i have made the chain go in the front big ring or wee ring or on different sprockets on the cassette..i am truly baffled and don't no what the problem is :S..i thought it could be due to a lose bolt or bit of dirt between the stem and bars or seat post clamp and saddle making strange nosies when weight or force placed onto them but its not as they have been well cleaned and not over tightened..any help at all would be great .
