Due to the junkyard-quality donor bikes, it's pretty clunky; but in spite of it all, it is almost as fast as my faired V-Rex.
I'm assuming the donor frames were cro-mo? I wonder about looking for some aluminum donors. It doesn't look too difficult to build a vacuum bag carbon fiber seat, but I'd sure use an "old hardshell" if I had one laying around. Don't you love it when you get to use that stuff that's been laying around collecting dust?
