i think someone else might have posted about this maybe a month or so ago. i'm not sure, though.
i biult up a fixed mtb maybe 2 or 3 months ago and things were going great for quite some time. the other day i take it to the co-op to put brakes on, since i'm throwing a freewheel on the flip side of the hub. i noticed there that all my chainring bolts had somehow come all the way loose, nearly falling out. tighten 'em, no biggie.
today i was taking a 20 mile ride and 10 in we pulled over. my chain tension felt bad, so i reached down to adjust it--it wasn't the tension. it was the bolts. one's gone.
what the hell is going on?
oh, and it's bulletproof cranks, rocket ring, and pyramid bmx bolts.
