Help--Noise driving me crazy and broke
I have a CADD 8 frame with all Ultegra or Dura Ace. Recently it started making noise when I apply heavy pedal pressure to the left (non drive side) pedal. I'm looking for a word for the noise. Is it groaning, moaning, squawking? You get the idea. This only happens when I am when I am grinding up a hill STANDING in the pedals. It never happens when I am on the saddle. I replaced the bottom bracket and crank, switched pedals, torqued everything to spec to no effect. I weigh 200 lbs and have strong legs so the pressure generated can be significant. What going on?
