Time-lapse video of me packing a Surly Traveler's Check (a full-size, S & S coupled cyclocross bike) into the backpack that with a little luck, will meet the standard baggage requirements at the airport and save me $160 one-way (rates for bike luggage just went up) on my domestic flight with Northwest Airlines. I did also manage to fit front and rear racks and fenders in the backpack.

Here is the bike carrying it all. Notice the backpack travel case is strapped to the front rack. Everything else (panniers, contents, lock, etc.) fit into the green backpack on top of the panniers. Find additional photos under Surly Traveler's Check in the photo gallery.
