I just got home from my first Park Tool School class tonight. I'm the only person in my class so its awesome. Tonight we went over tools, lubes, tire changing and chains (clean, repair, remove, etc.) I knew a bit about the first 3 topics covered tonight but I learned many new things and got an opportunity to ask questions about some problems I was having. I purchased the Park Blue Book of Repair about 3 months ago. However, I need to see things explained before I understand it. You get to work on your own bike. I think next week is brake and derailler adjustment plus some other good stuff. I don't see how you can go wrong by taking the class.
FYI, I recently purchased an Ultimate Pro Repair Stand from the REI Outlet Website for $154.00 (price included shipping). You won't find a better price on the Pro which is a very good stand. You'll find it much easier to do the repairs with a bike stand.
