The Lemond has some odd (not the best word) geometry. The top tub is longer than most frames and the seat tube angle is more relaxed which puts the rider further behind the pedals than most bikes.
There are bikes out there with similar geometry but I can't think of them at the moment. I'm probably wrong but Merckx comes to mind... You're going to have to do some searching if you like the Lemond geometry.
A warning, if you are very comfortable on the Lemond make sure that your new bike has similar geometry or you will be very disappointed.
