I'm planning on a very very light transamerica tour with Fuji Team Pro bike. It has a 56 inch C4 Monocoque-Carbon frameset with 16 and 20 spoke 700x23 (22?) Shimano wheels. I weigh around 140 and planning on a 20-35 lb. load. Any suggestions about racks or panniers? Does a trailer put too much stress on the forks? What exactly is the weight limit?
