Today's weight weenies reach for carbon fiber everything. What did weight weenies do in the mid to late 1970s?
I have a bike from that era that has the potential to be very light. I'm looking for period correct weight weenie tricks. Excluding drillium, that is.
Did people use hollow pin chains in the six speed era? Alloy cogs? Titanium or aluminum fasteners? Other tricks of the time? Can one still get this stuff today?
What did a really light road racing bike weigh in 1978?
P.S.
Regina Titanium freewheel and Regina Titanium chain. way cool, but cost a weeks' wages. Each. At wholesale.
