Pretty pictures, but in all a very shallow book about the basics of creating a bike by bolting together purchased componenents. Just one page devoted to discussing trail, and only a vague sentence or two on how it effects handling. Then, a complete chapter on how a pro shop fabricates a frame. Interesting, but anyone with the ability to actually make a frame won't be impressed by the knowledge presented, and anyone without the ability will be no closer to it by reading. The book seems thrown together; too much info here, not nearly enough there.
