Here are the bicycles I mentioned previously:
The first, blue in color, is a Super Course
Serial#184987 Top Tube=22.25" Seat Tube=23.5"
Chain Stays=17.5" Wheel base=41"
The second, white, is a Professional
Serial #E-7_5_74684321 Top Tube=23.25" Seat Tube=24.5"
Chain Stays=17.5" Wheel Base=41"
The last, black one,is a Competition
Serial #H1363 Top Tube=22.5" Seat Tube=23.5"
Chain Stays=17.5" Wheel Base=41.75" (interestingly)
All seat tubes are measured from center
of BB spindle to TOP of seat lug.
All top tubes are measured along the center
line of the TT from the center of the head tube
to the center of the seat lug.
Wheel base measured from axle to axle as currently
configured.
I'm not real good on angles, but they are all
a little slack by today's standards. Hope the
pics and measurements are of some help to you.
Last photo is of old guy (me) lifting Super
Course in air to demonstrate that it's not
all that heavy.
