a nr derailleur finally showed up for my alan today. but...................... the 980 that is on it has a frozen bolt, that won't budge. it's the 6mm bolt that goes into the dropout. the bolt moves in the dropout, i can see that. the bolt is actually frozen to the derailleur itself and won't spin and i can't get the 980 off. so far, i've soaked it in lube and tapped it with a hammer. it hasn't broken loose.
any thoughts of what i can do to get the 980 off the bike, would be gratefully apprecieated.
