Member [MENTION=360180]SpeedofLight[/MENTION] has been posting old articles from Bicycling magazine. I like these as the let members read about what was happening in the bicycle industry in a given year of the article.
Recently I acquired a copy of the "Consumer Guide bicycles" published in 1972 by Popular Library. It is in paperback book format. I think this was also published as "Buyer's Guide 1972-73 bicycle test reports", from Doubleday & Co.
With the Bike Boom in progress this publisher saw an opportunity to sell books. There is only one piece of advertising and it is for cigarettes.
This publication provides an insight into what types and quality of bicycles were available for 1972 and leading into the 1973 model year. The book covers domestic USA products from the manufacturers and the mass market retailers. Also some of the larger importers are listed and the brand names that they import.
The book reads like the material has been reasonably well researched.
The publisher says this is first in a series of annual publications. I have seen on the internet the Consumer Guide bicycle test reports for 1973, but this is the only other year that I have seen.
I think it is a good reference book for some aspects of the USA bicycle market in 1972.
