I have a 2010 Trek Madone 5.9 frame with a smattering of all kinds of Shimano parts for the groupset. I had a pretty crappy frame before (comparatively, that is). It was a used Leader TT frame. Also, I'm a big guy: 200+, 6'4", but like 14% body fat.
The problem: When I get out of the saddle and dance on the pedals, there's a creaking sound. It occurs with the downward force of my pedal stroke bilaterally. Is it in my bottom bracket? I also had a sneaking suspicion that it is caused by over-tightened chain-ring bolts. Is this a possibility?
