A bike isn't finished at the table it's built on. It moves to the tire pump, then to quality control, then to the repair shop if something's off, then to the packing depot to be paired with its helmet and lock, then out through the loading bay. Sponsor a station and your name sits on one link in that chain — and all 1,200 bikes pass through it.
It's the easiest way onto the build floor and the least work. We build it, we staff it, we run it all day. You don't need to send anyone or bring anything — though most sponsors turn up anyway, because it's the best room in Charleston that Tuesday.
