Hi, once saw a book that i foolishly passed up. It was a memoir of sorts of a guy who rode the GDR when he was pretty young and then came bck and did it again fifteen or so years later. The copy I sa had a close up shot of a rear cassete cluster taken from the back of the bike. I am just hoping that some one knows the name of this book and/or who wrote it so I can track it down. Thanks.
