Yeah there's a lot of junk in there that I need to get out. I did some scraping with the screw driever last time, I need to do more of that. It's a bike I bought off CL and the previous owner apparently wasn't much better about cleaning it than I am. Looks like the cogs are showing some wear, so I'd like to clean it to slow that from getting worse and just get it back in proper mechanical shape and take better care of it in the future. I figure once I get it really clean a regular cleaning in the future should be faster/easier.
