This noise happened a couple days ago, I retorqued the bottom bracket to spec (bolts really didn’t move any) and the sound went away for 15 miles. The bike is new and has about 150 miles total on it. Now the sound is back and nothing I do fixes it. It is a very loud creak that happens on the downstroke of the left pedal. Sorry about the excess noise, hard to get a steady video on gravel. Thanks for any advice!
