Re:
We are getting closer to completion ! sorry for the suspense of the final build and pics ( which should possibly be done within 10 days) :facepalm:
HEADSET
The main french company producing headsets at that time was Stronglight. Its light headset was the D6 in alloy and some parts in steel. Incidentally the P3 in steel is also supposed to be as light at 120 g

Catalog P3 acier D6 S5
Actual D6
But JPR ( Jean Paul Routens) also manufactured light parts and here is his attempt at headset lightness

Actual JPR
Well actually ther is not much competition : the Stronglight in alu is advertised at 120 g
but the JPR – sometimes engraved BF as mine - is advertised at 68 g !
Luckily my Bernard Carre was already equipped with the headset as it is very rarely seen in France, or very onerous on ebay
9 ) FREEWHEEL
There were several french manufacturers of freewheels namely : Atom, Maillard, Cyclo
But at a stage some were swallowed by others but the make names still existed so it’s a pretty confused scene !
On the scale passed steel freewheels
A Cyclo 72 5V is 294g
An Atom 5V is 327 g
A Maillard Course 5V 381 g
But at a stage Maillard made an effort for a light freewheel.
It was manufactured in alloy - sometimes dubbed Zicral - easily recognized as with a bronze or brown color
Maillard Catalog
The result was amazing !
The body alone is 80g and the 5V I build is 172 g - an enormous weight gain. It will therefore be mounted on the wheels of this full french light
10) TUBULARS
Well for a lightweight, I can’t really pass on tubulars so my bike will have a second set with tubulars.
Mavic and Wolber Super Champion were the main competitors in France for rims and Wolber the strongest on tubulars
Super Champion was actually a stand alone company initially but it was later bought by Wolber.
Rims Array ( USA !)
Ad Mavic Rims
Wolber Tubulars
The wheelset chosen finally is equipped with rims Super Champion Competition Arc en Ciel on very classical Mavic sealed bearings hubs (desctibed earlier on in the hubs part) and period Wolber Neo Pro tubulars.
The hubs are actually Mavic 500, the very first version of these Mavic hubs which became leter the 501
The Arc en Ciel is not the lightest rim from Super Champion but reasonably light at 345 g ( the Performance was 305 and the record du monde 330g)
The weight is really an enormous progress on the clinchers !
Front with skewer is 1060 g
Rear with the Maillard Zicral freewheel is 1260 g
Comparison with another set of tubulars was done
A pair of Mavic Special Sport on Normandy Luxe Competition small flange hubs with skewers and Schwalbe Montello 300 and same Zicral freewheel is
Front Wheel 1130g
Rear Wheel 1390 g
For info Clinchers weighed previously ( Module E on Pelissier 2000 professionnel and Michelin Bib) and same freewheel
Front Wheel 1250 g
Rear Wheel 1570 g
