My KHS MTB is aluminum frame, with almost all late-90's Deore XT and LX parts on it. Most everything is aluminum as far as I know, including rims, crank arms, pedals, and possibly chain rings, and it weighs right around 28 lbs last time I checked. My wife's new BD bike, with aluminum frame and stem, but lots of Tourney steel parts, weighs in at almost the exact same 28 lbs. How is that possible? The frame of my bike is heavier perhaps?
Not that we'd ever do it for a $300 bike, but I suppose switching the components to more higher-end, with more aluminum, could potentially make her bike substantially lighter than my MTB, no?
