I have a Specialized carbon "expert with 12000 miles on the clock. A creak started appearing when applying power to the pedals. It changed to a loud click and as it was in sync with pedal rotation I assumed it was bottom bracket related. My LBS fitted new bearings, possibly against his better judgement but he had tried other solutions first Tightening pedals chairing etc to no avail
I still have the click but it only appear towards the end off a long journey ( 80 miles or more) and it still seems associated with a slight creak.
I'm stumped. Any suggestions other than earplugs or new knees?
