I had a jerk creaking sound getting gradually worse in my crankset. Alloy frame, threaded bottom bracket and always serviced and tensioned to correct spec. I've greased the thing like you wouldn't believe and had it on and off at least ten times in a month and still the creak persists. "Fuck ya" I thought, "I'll get a new one" and so I did. I whipped home one lunch break and chucked it in my frame and did the driveway test to inspect. You wouldn't believe it, the same creak in the same audible tone each time I put either foot down. I invented a few new swear words that lunch break and had just enough time to pull the thing off ready to hurl it over the fence. In somewhat of a chance discovery, I had a close look at the non drive side part of the spinlde where the crank arm is pressed on and there's a small 1mm think spacer on there that I always assumed was just a plastic fitting.
It isn't.
It's three wafer thin spacers that had grit between them and was enough to make the sound and echo through the glorious hollow alloy tubes of my frame to sound like the soundtrack from War of the Worlds. I took them off with a pick, cleaned them in the nearest alcoholic substance I had and dabbed some grease on them. At this point I'm late to get back to work but fuck, I just need to know! I hastily whack the thing back together and proceed to ride up and down my drive way in such soothing silence. So much ambiance, so much relief..................... so much fuckwit.
