"in the 80's you just carried a spare tubular or two (depending on the length of the ride) and the house keys, and a pump,
no helmet, no eyewear, no multi-tool, no cell phone, no levers"
I must have been ahead of the curve!
In 1974 my Paramout was equipped with no less than a Cinelli quick-release tire bike holder (Bikeology single sew-up with two small side zip pockets). It was the much less techy solution to today's twist-lock back mounts but much more classy than the plebeian toe strap!
I also ALWAYS carried a spoke wrench. Do you guys have any idea how often those crappy French 3-Star chrome-plated spokes popped?!?! Rivoli / Cyclo...back in the day. Chain tool sometimes. Tiny derailleur screwdriver only if you knew you couldn't find discarded beer pop tops (remember those?) to use on the simple, slotted screw heads of the day.
Indeed, the Impero rode only in the vertical position with a Campy umbrella clip in the pre-molded pump handle days. One clamp-on steel cage per customer, please!
Presta-to-Schraeder adaptor was always threaded to the toe clip screw. Always.
As far as no helmet in the 1980's...I will admit to having attended several UHWA (Ugly Helmet Wearers Anonymous) meetings for the sin of adopting THIS!

That's right, not as cool as Belov's skullcap, but I was sprinter-aero-chic before snap-on helmet covers and the Gyro 'hot head' became awesome!
Edit: Oh...and who could forget wrapping a roll of Jansport instant sew-up rim tape in foil so that when it melted in your tire bag the glue would still kinda sorta still be on the tape!
