My bike seems to all of a sudden developed a creaking sound when I pedal. It appears to be there in every gear. Bu t I noticed it appears to only happen when I put pressure on the left pedal. What could it be ?
It could be:
- The pedal itself (even if it moves freely)
- The other pedal
- The bottom bracket
- The saddle
- Loose crank
Try to isolate each one of these by taking the weight off each in turn.
I was recently convinced my saddle was creaking as it only happened when sitting down but it turned out to be the left pedal!
