"Bicycling" was a heck of a magazine in the old days. Very good articles about how bikes are made, and how to make them work better. For example, an article about adjusting PSI EXACTLY for the weight of the rider to get the best performance from a tire. More recently, "Bicycling" editors have told readers to use the PSI on the tires, which is the WRONG advice if the rider weighs less than 150 pounds. But, the current generation of editors seem to know very little about bikes, although they are experts on how articles can look like advertising.
Some of the old issues had "buyers guides" listing all of the specs for road bikes that were available. It would be terrific is someone could scan those old buyers guides, and post them for Forum members to read.
