The Paramount was developed for track and road racing by Emil Wastyn, a 6 day racing frame builder, mechanic and Schwinn dealer in Chicago, who immigrated from Belgium. The Chicago Schwinns were among the most bomb-resistant bikes ever built, and they were built with unique technology . With the exception of the Sports Tourer, Super Sport, and Superior, they are welded, not brazed. The head tubes look as if they were fillet brazed, but they weren’t. There are necked-down parts that fit into the top tube and down tube, like internal lugs.
Here the issue is implications of use or manufacture of a good or service which aren’t available to anyone when initially transacted or provided. The use of fossil fuels (global warming, acid rain, particulates) comes to mind. Thomas Midgley, the most dangerous inventor in history, is another example. Two of his creations, freon (chlorofluorocarbons) and leaded gasoline both threatened or harmed more people than any other single person in history. Because they weren’t knowledgeable, that’s the whole point.
The West Coast had its own cast of characters, including Tom Ritchey and Eisentraut. Starting in 1971, Schwinn outsourced excess Paramount production to Pioneer Manufacturing of Racine, Wisconsin, owned by Don Mainland. Don was an accomplished bike racer as well as successful industrialist.
The most common difficulty is that the Schwinn 26 x 1 3/8 (I. S.O. 597 mm) interchanges with the British 26 x 1 1/4, not the British 26 x 1 3/8 (I. S.O. 590 mm). While the Paramount had proven itself the most successful American racing bike of the 20th century, it became apparent that changes needed to take place or its reputation would be lost. We offer service contracts on a monthly, bimonthly and quarterly basis.

This bike was only a year old at that point; clearly it wasn’t designed to be ridden beyond an initial burst schwinn dealers of post-purchase enthusiasm. It’s the only time I’ve ever seen the failure of a bike frame. As long as it isn’t left out to rust, a lugged steel frame will outlive its owner.
Geometry also went through changes in the 70’s with shorter wheelbases, steeper head angles and steeper seat angles replacing the established geometries of the 60’s. These became fashionable for criteriums – the fastest growing type of race in the US. Components from Campagnolo continued to advance, but a more radical revolution was taking place in tire technology from Europe with the introduction of 700 x 18C and 700 x 20C tires.
At the close of the 1920s, the stock market crash decimated the American motorcycle industry, taking Excelsior-Henderson with it. Arnold, Schwinn, & Co. (as it remained until 1967) was on the verge of bankruptcy. With no buyers, Excelsior-Henderson motorcycles were discontinued in 1931.[5] Ignaz’s son, Frank W.
