TrojanHorse's maintenance thread got me thinking. I am mechanically enabled, just don't have the right tools for working on bikes, but I like tools, so why not buy some more. It probably won't take long to make up the cost by doing my own maintenance. So, I already have a Topeak Alien 2 tool, and I think you could tear a bike completely down and rebuilt it with that thing, it rides with me whenever the bike goes out. The first maintenance issue that needed to be addressed was the incredibly filthy chains on my bikes, so I got some Chain-L lube, and a Park CC2 chain check tool. The chain on the bike I ride the most is shot, 1.0% on the chain check, so at least I have one chain less to clean. Hopefully I caught it soon enough, but only the last 250 miles on that chain are mine. If I didn't, it is just a 7 speed freewheel, and when I replaced the rear derailer, I did get one that is 9 speed compatable.
