I just finished the same book. I found a reasonably priced used copy on Amazon. It was a very interesting book, one that I found hard to put down. I was pretty much away from cycling in general by the late seventies, so it filled in a lot of missing details.
A couple of things that stuck in my mind was the part about the Centurion LeMans bikes, which were originally conceived as a Raleigh Grand Prix made in the Far East, but certain powers at Raleigh nixed the idea. The remaining bikes were rebadged as Centurions. When I first saw them as a kid, I thought they were just a Raleigh knockoff. I never knew they were intended as a replacement.
I also learned a lot about Schwinn's competitors of the day, such as Nishiki and Trek. I owned a Nishiki in 1973, but never learned much about the company.
