update: the new chain is amazingly better than what was on there. i can't believe i let the old chain go for so long, and how trashed it is. just the difference in sound (now lack of sound) while pedalling is incredible.

the new chain is shifting great and hasn't skipped yet. there's a problem shifting from the middle to inner chain-ring, but i think that's been fixed with a limit-screw adjustment.

while waiting for the chain i did get a little excited and order a new cassette and crank-set which i'm now in no rush to replace, but it'll be nice to have spares when the world ends, in a few months
