Not a longer "wheelbase", but a longer top tube. If you ride a 56cm frame, get a 55cm Lemond. I road a 98 Zurich for seven or eight years, loved the ride. One caveat you may want to be aware of- My Zurich was made during that time period when high performance road bikes were being manufactured with very little room between the fork and stays for larger tires. I never could get even 700x25's to fit without rubbing.
