Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

Besides, actual metal density doesn't correlate directly to atomic weight, since the various metal atoms pack differently. for example Gold has a lower atomic weight than lead, yet is the metal is denser.
