He did oil my chain, tighten my spokes and adjust my brakes but he didn't think they would cause the sound I recorded in the video. He put it on a rack and looked for some chain rubbing but couldn't get it to do anything out of the ordinary. Even did some short sprints inside the shop and its as quiet as the day I bought it. I'm kind of at a loss really.
