Yes, i've already read the sheldon brown article, but i didn't really find it very helpful. Would it be possible to take them off by hammering the pin out and then maybe taking a hammer and a screwdriver or something and trying to knock them loose? And before i do this i should probably ask, would i be able to put regular cranks from my other bike on it, or do cottered cranks have different type of BB that they wouldn't fit on. Sorry for vague questions
