I noticed the creaking noise (first seconds of the video). After trying to tighten and touch up on any bolts I found that loosening the side bolt eliminates the creaking, but it introduces very little amount of play. The play is felt especially when I put weight on either end of the flat bar. When I bike normally I feel it a little especially on turns or when I shift my weight around. The bolt that I adjusted on the side is quite tight, I can barely tighten it more after it reaches a creaking point. On my previous bike I had a similar issue and tightening the bolt removed the creaking, but on this bike I am afraid to try to tighten it more. What do you guys think, should I choose the creaking or the play, or is there a proper way to fix this?
