So a person could take today's aluminum and carbon fiber components and an old Schwinn Varsity frame and build up a 16, 17 pound bike if he wanted to. That, or he could take a modern carbon frame, slap on some steel clinchers, a steel crank, steel this, steel that, and wind up with a bike that weighs over 30 pounds.
