In our technological age nothing stays the same for long. What may have been true of a material in the past may not be true in the future or even in the present. Rodriguez Cycles now has a steel model, the Outlaw, made with the latest high strength tubing and it weighs just over 14 lbs. http://www.rodcycle.com/

I ride a Specialized Secteur, aluminum frame, that is plush but I use 28 mm tires with wide Velocity A23 rims.
