I can't remember where I saw it, but the numbers I saw were 5'9" (so yeah, 1.75m) and 135lbs (69kg = 152lbs).

ps. the reason I said that initially is because of the headshot of him on the right side of the official tour website today. http://www.letour.fr/2006/TDF/LIVE/us/1800/index.html <- right side, middle picture. I know I have a giant mellon, but he's the only person shown with a loose fitting cycling cap. (not to mention the sunken cheeks). SKELETOR!
