I just put one of these on my Lemond, it a Serfas MX-2 Dorado. It's good and flat across the top, and wide enough that my sit bones don't feel like they want to roll off the edge. Good support too, not a piece of overly thick sponge like the original Bontrager saddle-never did get that to where it felt comfortable. Looks like the image didn't post so here's the link:
