I like to think I'm getting good at tracking down clicks and squeaks on the bike, and at the same time try not to obsess as much as I used to about them. But... My Guerciotti had been creaking terribly recently, especially during out of the saddle, high-torque efforts. Had this before and it was often the BB; so I spent an hour or so removing the crank, removing the BB, cleaning inside the bracket (full of grime, haha, culprit found), re-lubing and re-assembling nice and tight. Headed off today for a lunch ride and the whole frame is creaking worse than ever! Oh well, I didn't tighten the pedals, maybe they're the culprit. Or the handlebars? Hmm. Starting to get annoying... Then I suddenly remembered I haven't checked the quick releases recently. Get off. Rear is fine, front is okay but I guess it could stand to be a bit tighter. Tighten a quarter turn, close the lever. Get on the bike, start riding. Absolute, total, silence. A reminder again, when chasing noises do the easy stuff first.
