The ability to swap out components before you buy is what is interesting me the most about Neuvation bikes (other than the price). At that price-point, wheelsets and other components can be pretty iffy, but the ability to dial in the important stuff at little or no cost is a big plus to me. Every review I've seen of the framesets are that they're as good or better than other bikes at that pricepoint, and the weight isn't all that bad.
I'm looking at a Ultegra F100 myself, as a solid crit bike.
