i'll check the phonebook when i get there - oldschool style.
i'd say "have fun in the rain..." and sneer, but la is totally all sf'ed out apparently. rain clouds follow me. gee wizz.

. that was my first thought today, and i first heard the sound while sprinting, so it's safe to say i spent a short moment scared ****less. anyway. it's got rpm cranks, fuji wheel.

(( i don't have any money and can't imagine going more than 48 hours without riding my bicycle. i might lose it. 
new theory: i actually noticed while moving my bike around a second ago that my SEAT made a creaky noise! i'm hoping it's that, but i'm still sketched about the way the cranks look. not to mention having a creaky seat... wtf?
on that note, my bars also creak. they are some random no name chrome chopped drops i got on ebay for a few dollars because they were already chopped and i'm lazy. ever since i first put them on, they've creaked when i put weight on the front of them. i've tried all manner of loosening and tightening the stem bolts, to no avail. it does it all the time, and it's annoying as hell. suggestions?
god damn i can't wait to build my own bike from the ground up... partially so i don't have any more of these stupid questions, and mostly so that i know it's dependable. sigh, to have a half a grand fall in my lap...

dammit! stupid seat. that's what it was for me too. like a million times. we always think its the most complicated problem involving bottom brackets and tapers and its as simple as right under our dumb-lazy-assses.
check your bottombracket/cranks anyhow. take it all apart and get to know it. its fun
as for your bars: tighten stem in both places then if still creaking - have fun with the headset!

Get better bars
I think it might be just the metal flexing. Do they bend a little when you put all your weight down on them?
edit: stem might be flexy too. I used to have a cheap modolo stem to some flexy aluminum bullhorns that were similar in stiffness to a large rubber band. if i put all my weight down on them they would flex about 1/2 - 3/4 inch. they were noisy. Then again on that bike the headset was garbage too.

and building bikes up from scratch is lots of fun. Took me 4 months to afford all the parts though, siiigh.

also, how do i make my seat stfu?
finally, i have tightened and retightened my bars, they still creak incessantly. as for the headset, i'm pretty sure it's fine and that if i put my old fuji drops back on (which i don't like-- those newfangled 'ergonomical' drops are strange), the sound would cease immediately. which leads me to this:

this image is huge, but i'm too lazy to resize and reupload. so yeah. that's my bars when i first taped them. man, the brake looks weird now. i finally took it off a few weeks ago after i hadn't touched it once since the week that i got it. i was keeping it around as a safety measure, but i've started skipping and stuff like that so i don't really feel that it's ever going to do me any good. if anything i probably would've just ended up going over the handlebars. so anyway. yeah. that's them.

ps: do you work security at the dorms? i almost applied for that job last semester when someone quit, but i was feeling lazy and still living off of my college fund (veteran's affairs... blah blah blah) so i didn't. i want that job! wait... i'll just repeat this in pm. k. i'm shutting up.
a hundred thanks to everyone in this thread... you guys rule.

Now that I see the bike maybe the noise arent the cranks... maybe are the pedals, a bb cup, or the stem/handlebar. Unless he heard that thing all the time. and if thats the case I dont think are the cranks at all or a BB cup. Usually cranks are noisy when u go over the pedals and only in one position, when seated they dont do any noise. The stem/handlebar do noises time to time if isnt tighten enough. It could be an spoke. Did u check the spokes in the rear wheel?
