Today I finally got around to getting all the built up muck and grime off my commuter. My wife did not appreciate the cleanliness of the cassette and chain, so I figured I'd share with some people who might appreciate it. Unfortunately I forgot to take a "before." picture. I use wet-lube, so every cog had caked on grease/muck, the chain looked like it was dripping with slop and it was black and brown. Here's the after: Pic of the drivetrain and then the whole bike all spic and span.
