Big changes at Indy Fab. People coming and going. Fab moving locations. BTW, $4500 for a 3 yr. old bike with "battle scars" doesn't sound like any kind of a deal. Zero Grav brakes are a weight weenie fav, but performance my not be on par with new Campy/Shimano. With custom, you can get a brilliant paint job if you know how to spec it and any geometry tweaks you may need.
There are deals to be had for lots of great bikes between $4.5-6K.
