If we could have sections for
wheels
cranks
bars
etc
everyone post pics in those sections and a discription and year .
Example
Redline 401 Flight Crank - single pinch 1981
a six splined spindle had full wrap around pedal bosses and wrap around pinch bolt bosses.Introduced in 1981
pic of crank here

would be handy when searching for that right part/year for your build
Cheers
