so for a while now, my cranks on my evil would get a little sloppy...say when you are preloading for a bunnyhop, one crank would dip down a bit, say 5 deg, so they weren't exactly 180 deg from each other. tightening them would help, but only for about 10 seconds.
i thought the issue was related to tightening the cranks w/o removing the self-extracting bolts, and gradually wearing down the splines of the arms themselves. it started to get really bad recently, so i decided to get a new set of crank arms via ebay.
they came in the mail friday, so i pull my old cranks (driveside first; replace the spider because the cranks i ran had a DH spider and chain ring spacing (can't believe i had the right tool)), and then i pull the non-drive side.
doh! now i know why they felt like crap. i'm surprised the thing just didn't fall off. good thing i just screw around w/ this bike on the street. last trail ride i did was w/ splat in nam in dec. so now it's off to bb searching.
driveside (what it should look like):
non-driveside (bad):
