Most road frames can weigh from 3 to 4.5 pounds depending on size and, of course, tubing specs. Braze ons, brake mounts, crown and drops all affect this too. As the weight gets lower more expensive tubes are to be expected. Then the skills in joining all these choices start. Having said all that the components are the larger weight aspect. My choice is to blend the frame and the components to a mix that reflects the expectations. Then i ride the damn bike as fast or slow as my conditioning allows... Andy.
