finding where the noise comes from
Ok straight to the problem, i suspect that a clicking-creacking noise comes from the chain at the chainrings, is that possible? it is not strong but i hear it on every pedal stroke except when i climb hills under heavy load it seems to not make noise. i think its not my bottom bracket as it has not play at all and cups seem tight, front derailleur is not rubbing on chain, i almost thought there was the spokes of my back wheel and i tighten them.
my bb is hollowtech 2 ultegra 6600, the chain seems moderate or more wear so i will change it very soon, the chai rings show little wear but lots of life left (didnt even started to show any shark fin) and they are completely straight.
only other clue is that the frame is steel( not any damage anywhere) but may it be flexing so much? only pedals left to check but they seem ok, any suggestions? Is it the chain you think?
sorry for my bad english
