I would say most of the weight would be in water and food and cooking gear alone. I like to drink lots of water when I ride, so on a tour I would carry up to 2 gallons at a time, than again maybe my weight would be much lower than 100 pounds. I don't see how I could use panniers on the front with a Rock Shox fork. I guess I need to find my calibers so I can measure the spokes, they look the same size from the hub to the rim.
