okay, so after carrying our bike sans wheels to another city, i've decided i want to make one of those...uhm. things. my wife calls them "chain snugglies." i don't think that's the official name for them.
anyways. you put them in your rear axle with the chain to keep it all nice and tight. and clean.
what are they called, and where can i see pictures? (i don't have an old hub lying around, so i figured i'd try to make one from other parts.)
