Due to the above, today I brought the Baconator. When I last put this bike away, a few weeks back, it was running silent, except for a rare whimper from the 48yo saddle. But today, creak-creak-creak on every left downstroke. No difference except the season. I could feel it in my toes. No time to figure it out, had to ride... I think it's the crank arm bolt or the pedal thread. I hope I haven't rounded them out by this afternoon. I will torque it when I get home.
