It's not completely rusted out to the point that I'd be worried about riding it. However, the cassette, chain, etc. are pretty dirty so I will probably try to clean that up the best I can without taking stuff apart at this point. I used this bike back in the day and then had it sitting around just for the occasional ride. Now that I'm more into cycling I am thinking about at least trying to clean up the bike and see how good the condition is. What kinds of bike cleaning tools are recommended? I can use them for both bikes. Thanks!
