Alright guys, I've got a creaking noise that I simply cannot pin down. I've tried everything I can think of, but it keeps coming back. Here is a description of the noise:
It is a creaking noise, similar to what you would expect from a flexing frame, or a taught brake cable forcing the housing to rub on something. It is actually a creak, not a squeak or a click. It seems to be timed with my pedal stroke and is most noticeable when I am climbing or pushing hard on the pedals. When I apply significant pressure to the right pedal in the forward position while stopped, I can make it creak as the frame flexes.
Now, here is a list of things I've tired and notes I've taken:
There are no noticeable cracks in the frame.
I have regreased the seatpost.
I have repacked the bottom bracket twice.
I have swapped pedals--no change.
I don't use clipless pedals.
I have lubed all cables and component attachemnt points.
I have regreased the crank bolts, tightened them.
I tried greasing the spindle taper, and leaving it ungreased--both to no avail.
I have checked the handlebars and tightened everything there as best I can.
I have greased the contact points between spokes.
I have oiled the derailleurs and tightened every other nut and bolt I can find.
One special note: I recently removed the rear wheel to tighten a bearing cone. After putting the wheel back on, the noise temporarily went away. The noise is now back, but the bearing cone is still tight.
Some have told me it can be the BB taper as it is rounded off can make this noise, but the tapers still look pretty good.
Does anyone have any ideas of what to check?
