I adjusted the HS, hit the road, and the bottom bracket creaking had disappeared. The bike is super quiet, even with a Thompson Elite post.

The deal is that I could pedal out of the saddle or put my foot on the crank holding the saddle and bars and produce a nice creaking -- but that was also side-loading the front wheel/forks/HS and probably causing the HS to creak -- but it was an unmistakable BB creak. Again, I think that BB creaking can be a lot of things besides the BB.

Most people blame their BB of the creak. Most of the times it is unjustified. My first suspect is saddle and seatpost.

Clicking is often the pedals themselves especially if it happens when you're off the saddle too.

I had awful BB creak last month. Tried lots of things but in the end it
really was the BB, worn out after 25,000 km. It had actually out lasted
my previous bike frame.

Agreed. I remember a time my "bottom bracket creak" was found to come
from my saddle.


Once a mysterious clanking noise that just had to be somewhere in the
drivetrain turned out to be a coin and a chapstick in the pocket of my
jeans.

Well, the leg is part of the drive train.

In one spot in the crank revolution on the Madone when pedaling hard it will "CLICK". I would think that if it were the BB that it would click all of the time at that spot. With your posting I might try cleaning and tightening the headset again.

You may in fact have a bearing issue, but it never hurts to clean and lube the headset. Like Frank said, seat posts are great resonators, too -- but if you're getting clicking out of the saddle, that's unlikely.

IME, the most common cause of clicking and creaking is the rear dropout/axle on a QR bike. The clicks I couldn't solve turned out to be broken metal frames.

-- Jay Beattie.


Thanks for the object lesson.

BTW, how exactly does one treat the rear dropout/axle creak? Just
grease the dropout faces and/or locknut faces? Friend just told me
about a mystery creak he had.

Mark J.


Usually solved with straightening the wheel and tightening the QR. I've used a little grease, but I'm not so sure that is a joint you want to grease. I do grease the QR skewer and cam to the extent possible.

-- Jay Beattie.


Ok, I thought greasing the dropouts sounded a little dicey. I'll tell
him to grease the cam and tighten.
