Since i jsut got home from work I missed the entrance of this, and eventhough in the book it did talk about his spying, and didn't use the model in the TDF.
This bike was the famous "secret TT bike" that he talked about all during the winter months, but in fact the bike he used in 2004, was basically the same bike as the year before. The difference, was the pedals were closer together (By 18 mm I believe), but the bike produced slower finishes in the last few kms for Lance. The bike though proved to do wonders for Ekimov and a few others the book named. The problem with Lance, was something along the lines of his misaligned back or something along those lines.
You wrote the book title is Tour De Force, by my copy of this book is simply titles Lance Armstrong's War. The book is not really a pro Lance book. IN fact, the book has a chapter where he talked with David Walsh (The author of LA Confidential), talking about how in fact Walsh liked Armstrong back in 1994, and in fact wrote about him in his book Inside the Tour De France. He came to the 1999 TDF seeing if the speeds would slow thanks to the Festina scandal, but in fact they were up, and through Armstrongs actions, Walsh felt like he was somebody with something to hide. IT also include comments from Landis and Hamilton, which talk about Armstrong being an almost impossible person to get along with as friends.
