Hello. Sorry for the shameless plug, but if you are looking for a different book about bicycle racing, you might try my own book, The Long Season.
http://www.amazon.com/The-Long-Season-Bicycle-California/dp/1891369326
The story chronicles one year of amateur racing in California. It also closely follows the European professional season in 1995. My intention was to describe the feelings and passions of bicycle racing, as well as to communicate something of the history and inner workings of the sport. There is also, dare I say, a love affair.
I wrote the book when I was young, and, in retrospect, many parts make me cringe in embarrassment, but there are other parts of which I am proud, including the whole process of writing and finally publishing the book, which itself was a long journey. Some people seem to identify with the book, others don't, but I can honestly say that, as far as I know, nobody has ever written, or tried to write, about bicycle racing in the same way.
As regards other books mentioned in the posts above, I agree with the recommendation of Tim Krabbe's The Rider. Another great book which I am surprised nobody has mentioned is Paul Kimmage's Rough Ride. I can also recommend Robin Magowan's Tour de France, and Dino Buzzati's Giro D'Italia. There are also several books, such as Paul Fournel's Need For The Bike, which are not exclusively about bicycle racing, but explore cycling in general with a philosophical perspective.
Finally, throughout literature, there are various references to or descriptions of bicycling and bicycling racing, some of which are quite beautiful. Searching for these rare passages is a rewarding quest.
All the best,
Bruno Schull
