Replaced the cassettes on two of my bikes years ago but never did anything with the ones (these) the bike shop took off. Been boxed up for years so they'll need to be cleaned a little.
Shimano Tiagra CS-HG50 - 9-speed 12/25 - asking $10

I live 1 block across from the Waterfront (green line) metro stop and also work in the Farragut North area if it's easier for you to meet me there.
