Handlebar noise
 

My handlebar makes noises. Mostly when i put pressure on them. I inspected for cracks, lube and tighten all the bolts that holds the handlebar together, but it's still making noise. It has a adjustable stem. Which I have it angle all the way up to the highest level.

Any thoughts of why it is making noise or how to fix it?

Thanks in advance.

The creak doesn't mean anything, it's just slight movement under load where parts join. Adjustable stems are especially prone to it because the hinge is almost impossible to tighten enough. Start by spraying a thin oil, like WD-40, or any of the "dry" chain lubes where parts mate, and see if that helps.

If is still creaks, see if you can tell if it's from the bar/stem joint (common), the stem/steerer joint (rarely) or the hinge, (most common).

I've found the best way to cure stubborn creaks is to assemble using lapping compound (grit/grease mix) when assembling. The grit bites into both mating surfaces locking them to each other, and preventing any movement even with fairly low clamping force. Only be sure not to force the parts, like to straighten a twisted bar, without completely loosening the clamps. Otherwise the grit will cut into the parts when they move.
