this is so hardcore. today i put all of my leg strength, all of my endurance, everything i had into that quarter mile sprint. and i probably topped out at 30mph or something. i suck!

from eyeing it, i think it's safe to say the chainrings are okay. but that's scary.

checked the chain ring bolts, they are fine. not sure about the bottom bracket because i don't even know how to f with that s... like i said i haven't even gotten the cranks off yet.

for this and the post asking if they gave it a tune-up at the shop where i bought it, the simple answer is 'no.' i bought it on like december 2nd, haven't had it in a shop since mid-december. it's an 06 fuji track, so it was relatively new when i bought it... but i hear fuji factory parts aren't the best thing in the world. i've heard scary stories about their lockrings and/or spokes stripping out on their back wheels,
. 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.

the cranks have square spaces underneath where i took the bolts off, so i'm assuming the bottom bracket taper is square as well. but i still haven't gotten the cranks off, so i wouldn't know! anyway, cracks sound scary
(( 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...
