Park Tool School
Is anyone familiar with this program? I'd like to learn at least basic maintenance and having someone actually teach would be better than trying to decipher a book, especially since I currently know next to nothing about bike parts/maintenance.
If I remember correctly, you should be able to find some threads on the subject by searching the forum.
Years ago, I eBay'd a copy of the "textbook" that Park uses/gives in this program. It seemed pretty comprehensive.
Though I've never taken the class, I'd guess they do a good job. Of course, it's going to depend on the skill (wrenching and teaching) of the particular instructor.
REI also does a reasonable job with their comprehensive (not the free class) bike maintenance course.
