FYI, there weren't any carbon dropouts back when Trek called their molded carbon race bike "5200". I believe the first bike with carbon dropouts wasn't until Look did it in 2007 or so and the 5200 ran between 1992 and 2006, even though the replacement "Madone" series (also with alloy dropouts) came out in 2003.
