The bottom bracket on my '09 Madone 5.2 started creaking the other day. It is a press-fit bearing setup and the cups are 500 miles old from December. I had issues with bolt on BB's in the past and that was a sign that either it was starting to fail or that debris got in there. So, I pulled the cranks and cups and cleaned / regreased the setup and put back together. It is better .. though it will still creak on hard strokes.
- Would the bearings have failed that soon?
- Is there something else I should be checking?
- Would the BB shell potentially be the culprit here?
Thanks in advance!
