Creaking Bottom Bracket...
Iím having issues with a creaking bottom bracket. It started after a climb. It occurs when the left pedal goes over the top. Iíve taken it in to 2 different LBSís, where it was cleaned and relubed. After the first lubing, it started to creak after 25 miles. I then took it to the other place and the creak started again after 15 miles. Talked to the first LBS and the said it might need to be retightened. Took it out today, and it started to creak after about 7 miles. I then switched to some SPD pedals with mountain bike shoes. My main pedals are Speedplay Zeros with a pair of carbon shoes. It seems to creak in proportion to the amount of pressure being applied. More force=louder creak. Itís a carbon Scattante with about 600 miles on it. Iím a 300 plus guy as well, so I drop into my granny gear, trying not to mash.
Any thoughts? Can a BB loosen up in such a sort distance? If so, wouldn't it creak at the beginning of a ride, instead of after it "warms up?"? Could it be a bearing issue already? A crack in the crank or frame? Knock on wood, but it hasnít been wrecked. Thanks in advance for your thoughts and not beating me up about being a larger rider. Ha HaÖ
