Niobium is element 41, a transition metal. It was previously called columbium, but the name change was some time ago. Niobium bike tubes are steel with a wee bit of niobium alloyed in. It presumably changes the properties of the steel in some way I can't be bothered to worry about. -- Mark "viva chemistry" Anderson -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
