I am running 6700 Shimano chains with those stupid one-time hollow pins, so I don't really want to sacrifice another one. How easy/hard is it to disassemble the RD cage to fix this? If that's not too hard I would rather do this and keep the chain intact. If that's a bigger PITA I suppose I can find a break-off pin from another new chain I have on the pegboard.

Advice?
