i've got a Hussefelt stem and bar, and no matter what, it makes an awful creak. doesn't happen when i put side to side pressure, but landing, even just going off a curb, it creaks. i've had them for about 2 months and it just started a couple weeks ago. i took out all the bolts, greased them, and greased between the bolt head and the washer. nothing cures it. the only thing i could think that might cure it would be to replace the bolts with washer-less bolts. anyone know?
