frozen stem and seat posts
on 3 steel bike frames..i managed to free 2 stems, one alloy the other one steel. an alloy and a steel seat post. i had soaking in vinegar for a while.
one steel stem is still stuck.
i don't think vinegar did the trick though. i think it it was actually placing the posts & stems in a vice and wiggling the frame or forks left and right with an up motion whilst squirting CRC in there.
i managed not to damage anything including the alloy seat post and alloy stem and are re-useable. sweet.
my question is; what do you do with the inside of the fork tube and seat tube, do they need to be cleaned out - honed out? i'd imagine there'd be some corrosion in there.
if so...how would you do this?
