The best advice I could give to you is that if you don't want you're bike scratched up, crate it up in a bike carrier and arrange to have the carrier shipped back to your home. CNC will carry the crate up for you but will not transport it back. I did my first ride in 2003 and did just this crated it up to Boone via the CNC truck and then shipped it back home FedEx Ground. The only difficulty was finding a FedEx drop location. In subsequent years I've transported my bike up on my own vehicle and just been dropped off.

While the CNC staff takes great care in packing the bikes, there is just no way to prevent incidental damages.

Go to your local Lowes store and buy some pipe insulation, it is pre-slit to fit over pipes. Cut to size and mark with a sharpie each section where it belongs. Attach it(insulation) to the frame with electrical tape. You can even wrap your deraileur and brake hoods if you are really picky. Discard at the start or save it to use another time.
