I'm a visual person and like to go at my own pace, so a book often helps me, too. I recommend the Bicycling Magazine guide - it covers road and mountain bikes, and since I have one of each I went with that over the often-recommended Zinn guides. I also like it because it has excellent photos - I've been able to piece things together better with them. Lately I've taken my repair and maintenance to the next level - I took a couple classes at a local shop which gave me more confidence to tackle harder things. I found the Park site to be good, but sometimes more technical than I could handle at the first reading, at least. The videos at: http://bicycletutor.com/ are cool and watching them a couple of times before I head off to do something has worked well. Another similar site is http://www.expertvillage.com/video-s...nce-repair.htm which I've watched a few of as well. Crazy to have a laptop and book open next to my tool box, but hey, it's working!
