if i were to describe the sound its more of a clunk, similar to the sound when the chain engages the freewheel when you start pedaling from a stop or a coast. its not a creaking noise but more of a thump. when i first rode the bike i at first thought it was a distant hammering of construction workers. but i will test out your BB test that you mentioned.
