So you don't believe a guy who has actual contact with that bike. And the motive to lie is exactly what? Impress chicks?

But I suspect that weight reduction/optimization was mostly just left mainly to the frame manufacturers who came up with CF, Al and To frames that are way lighter that what was available in the 80's and early 90's and buyers would rather have more robust and dependable components instead....

I can believe that an MB1 is a very light bicycle as my 1990 Moulden XC mountain bike (rigid) weighs 23 pounds with a 24 speed drivetrain... the only real difference between it and the Ron Cooper is the extra weight in the mtb tyres which are 800 grams heavier than the road tyres on the Cooper.
On cranks... the Stronglight on my Garlatti and Sugino Competition on my Cooper are as light as most modern high performance cranks that do not utilize carbon fibre and even then, they are very close.
In their day they were among the lightest cranks money could buy.

Jan Heine is about as credible a person as you're likely to find when it comes to details about mid-century French randonneur bikes.
On page 46 of The Golden Age of Handbuilt Bicycles, Heine discusses how the 1947 Rene Herse bike featured on that page managed to achieve 17.4 lbs complete, including fenders, lights, rack and pump.

Every detail was reworked in search of a few grams saved. The front derailleur was made from aluminum, with a shortened lever. The cranks and chainrings were filed and reduced to an absolute minimum. Pedal cages were cut away, brake levers filed and even the pump was shortened to save weight. Because the extremely thin lower pump peg bends easily, the pump was mounted upside down! A superlight aluminum low-rider rack hel the bags for the 4 kg (8.8 lbs.) of luggage the bikes had to carry.
The frame was made from superthin 3/10 mm Reynolds 531 tubing (standard is 7/10 mm), fillet-brazed to eliminate the weight of the lugs, with a special twin-plate fork crown and ultra-thin dropouts. Even the derailleur spring was shortened. The saddle was modified extensively, and it bolts directly to a special seatpost. Of course, all bolts were machined from aluminum. The result was an impressive machine weighing just 7 kg (15.4 lbs.). The bikes were weighed without tires and innertubes to level the playing field, because lightweight tires were available only on the black market so shortly after the war. The complete bike therefore weighed about 7.9 kg (17.4 lbs.), including fenders, lights, rack and pump.
To prevent riders from riding too gingerly on the rough roads, speed counted in the results. Rene Herse assembled a team of fast, but careful riders. The result was a convincing victory, with the first four places among the men, the first place among the women, and the best tandem all going to Herse.
It is amazing that a machine from the 1947 technical trials has survived almost completely intact. A few parts have been changed and replaced, but essentially, the bike is as it was ridden in 1947.

The only exercise I got while at THE Ohio State University was 12 ounce curls at the Castle, Char Bar, North/South Bergs, VC, etc.
