Maintanance & Repair book recommendation
Here are two older books from 1988 that are well written, easy to understand, and show you how to fix bikes with common tools:
The Bicycle Repair Book
and The Mountain Bike Book
Both were written by Rob Van der Plas.
Obviously, these books are 15 years old, so some of the info is a little obsolete, BUT most of it is still right-on and solid, man (retro verbiage intended).
Seriously, if you see these books around, pick them up. They are meant for the 'Can-do' type person who just doesn't have a lot of bike knowledge yet. These are not books for the expert looking to learn something new.
