here a take out of the period from introduction of Bleu SSC in 1972 upto comercializing Argent 12 SSC in 1977
...
1972
Introduction of the distinctive Blue anodized "Bleu SSC" tubular rims for the 1972 European racing season, made available only to riders in the peloton.
1973
Wheels become Mavic's main concern, inspired by the first aerodynamic studies. In 1973, the Study Bureau examines a glass-fiber lenticular wheel. This is the first Mavic-signed wheel. Although track and road tested it is against the rules and is never used in a race. Aerodynamics however is in the air and Mavic continues its research.
1973
At races, Mavic makes available to all competitors a "neutral and free" assistance. Mavic's two key ideas are: a well-equipped car in front of the main body of riders to give immediate breakdown assistance to the leaders, and a complete radio liaison service between the vehicles (organizers, doctors, sports managers, journalists, etc.). The first Mavic assistance race was Paris-Nice. It was when he lent his car at the last minute to a Sports Manager whose vehicle had broken down during the Criterium du Dauphine Libere in 1972 that Bruno Gormand had the idea of making available a completely innovative "neutral assistance" better suited to both racers and organizers.
1974
A new logo - a yellow diamond inside a red rectangle with rounded corners.
1974
The birth of the grey SSC Paris-Roubaix (SSC Grey) hard-anodized rim. The first time that this treatment has been used on bicycle rims; it would be seen later that no high-end bike would be seriously considered that did not offer this type of rim. As of this point made available only for professional use.
1975
The Module E clincher rim. The first rim with double 'hook' bridge to seat a high-pressure tire developed by Michelin: the Elan. With this patented concept, Mavic started developing a new generation of rims for tires that rapidly benefited from all of Mavic's technological innovations. In the cycle-racing world the use of tubular tires gradually declines in favor of tires. Mavic commercializes their original "Bleu SSC" rims, now making them generally available for purchase by the public at large. Mavic introduces their Clear anodized and Silver hued "Argent 12 SSC" tubular rims. As with their "Bleu SSC" and "Grise SSC" predecessors, these "new" version of SSC rims were initially made available only for select use by professional riders.
1977
Mavic commercializes their Silver "Argent 12 SSC" tubular rims, thereby offering same for sale to the general public.
...
... the period for the project is 1975-1976 - so refer to the a.m. information I will have the choice between high-End MAVIC rims as follows
- Bleu SSC ( available from 1972 with old Logo and change in 1974 to Red Label for Pro Teams only - in 1975 commercialized for the public)
- Grise SSC (available from 1975 for Pro Teams, commercialized in 1977)
- Argent 12 SSC (same availibility as Grise SSC)
additional the famous popular GP4 Red Label ??? ( but I not really known when first time available for Pro-Riders)
