Dang,

I should have known as I sat on row 4 for 8 years in bike school before I graduated. Not even careful memorizing (really I did in Chemistry) of the periodic table could have saved me because of senility and brain warp style thinking. How a bout that Silver and Copper Cocktail though-- that must be bronze alloy - which is used to join tubing before high quality chroming is allowed to exist in the bicycle Universe.
