In the 30s in France, a group of people started the "technical trials", which, instead of testing riders was meant to test bicycles. This lead to some great advancements in bicycles, and some of the participants were astonishingly lightweight. Rene Herse had a bike that weighed about 17.5 pounds including lights, fenders, racks, and a pump (and a bell). Alex Singer had one that weighed just over 15 pounds with all those things, but that weight does not include tires. These super light bikes were made just to win the trials and may not have been intended to withstand many years of hard riding, of course. But nearly all of them had steel frames, which leads me to believe that, even in the 30s and 40s chromoly was pretty advanced. Even with the extensively modified aluminum components, it would have been difficult to put together a sub-18 pound bike if it had an 8 pound steel frame. I'm not sure how much these frames weighed, but I'd guess the lightest ones almost had to weigh under 4 pounds, certainly under 4.5.
Some of those bikes didn't even survive the trials. I've seen those bikes, I've ridden a Singer, colour me unimpressed. I'm not drinking the velo-orange/bicycle quarterly kool-aide (well not completely). 531/SLX rides better then anything that was being made in the 40's and OSX Platinum and Spirit both ride better then 531. The new 931 from Reynolds is exceptionally light and virtually corrosion resistant, but a bit too stiff for what I like.
