In the real world, bikes weigh more than advertised weights. A good quality size 58 touring bike with typical wheels and tires will weigh between 23 pounds and 26 pounds, BEFORE adding racks, lights and bags. If you use front and rear racks, four saddle bags, a handle bar bag, front and rear lights, etc., that 23 pound bike can turn into a 40 pound bike.
Weight is not that big of an issue in touring. If a 200 pound rider carries 50 pounds of gear, food, clothes, and water on a 25 pound bike, the total load is 275 pound. On a 35 pound bike, he is pushing 285 pounds. With high quality tires and wheels, I doubt anyone can tell the difference between pushing 275 pounds and pushing 285 pounds.
