Creaky BB
been chasing an intermittent creak. I replaced the pedals last year and that wasn't it.
Checked seat, handlebars etc. Quite sure it's the BB.
Not so much a creak, more a rubbing on the downstroke of the left pedal. It had been intermittent, now it seems more regular.
Cannondale 2008 CAAD9, 2008 I think. It's all OEM except the changed pedals. So it wouldn't surprise me that the BB needs help.
I bought it 2nd hand and have prolly put 1000 miles on it since I bought it a decade ago.
I'm reasonably comfortable mechanically, setting the chain, crank etc., right and have made them quieter than the tune up my LBS gave it.
Is the BB better to be done by a shop, owing to tools and experience or not a big deal?
