Recently while riding this terrible sound started appearing while I was climbing/putting down more than 200ish watts.
I had the bottom bracket replaced, drivetrain cleaned, shift and brake cabling tuned, seatpost and all other bolts torqued to spec, derailleur pulley wheels replaced, pedals taken off and regreased. Took the bike out today and the sound is still here. It's a 2×10 spd set-up with FSA front rings and shimano 11/10spd chain and 10 spd cassette.
Any ideas?
