Jan, the previous CR threads about "drillium" were mainly mine.
Ken refers to it as an "over used california-ism"? I had heard that he was irritated by my Peter Johnson bike with the Frank Spivey drillium parts winning Best of Show at last month's Le Cirque. Funny.
The practice of drilling parts actually dates back to at least the mid-1930s and undoubtedly predates that. The parts on Eddy Merckx's bike in the late 60s (not the mid-60s) were Frank Spivey's inspiration for the parts he started doing in the late 1960s.
Masi said the holes in Eddy's brake calipers were for cooling and not lightness according to Ken? Possibly something has been lost in the translation?
As I mentioned before, drillium (as practiced in California) was actually more about an obsession with one's bike and customizing the parts than it was about making the bike lighter.
Spivey never wrote any articles but he was among a group of people (including Peter Johnson) featured in a May '90 Bicycle Guide article by John Derven on the drilling phenomenon in the late 60s and early 1970s.
