Lugged bicycle frames, for example, are now manufactured by automated machines.Custom framebuilders still provide fillet-brazed construction, and tandem framesets were often fillet-brazed when lugs to fit their frame angles were not available.Arnold, Schwinn & Company was incorporated in Chicago in 1895, during the boom in bicycle sales of the 1890's.At that time bicycles were a fashionable but expensive mode of transportation for adults. originally produced standard light adult models weighing 19 to 24 pounds, and priced from 0 to 0, a lot of money in those days.During the 41-year span there were a variety of Schwinn fillet-brazed models, but details of early models are difficult to trace.This article describes Schwinn's final high-volume series of fillet-brazed bikes, the Schwinn derailleur bicycles of the 1960's and 1970's seemed to be either heavy (but sturdy) welded models, or much lighter but expensive Paramounts.With these models Schwinn achieved a nice balance of frame rigidity and smooth handling.Although they were fabricated in the same shop as the Paramounts, from there Schwinn's fillet-brazed frames took a different production path.

Schwinn's policy seemed to be to finish the fillets to the extent that they are visible at first glance.For 41 years, from 1938 to 1978, the Schwinn Bicycle Company of Chicago offered a unique but little-known line of specially constructed lightweight bicycles: The fillet-brazed chrome-molybdenum models, which were tucked into Schwinn's model lineup between the lugged Paramount and flash-welded models like the Varsity and Continental.Until the recent rise of quality TIG-welded and composite bicycle frames, most high quality lightweight bicycles used lugs (external metal sleeve fittings) to join their frame tubing.(The author does not know why lugs were not used for these frames.

Perhaps in those days manufacturing lugs was more expensive than hand brazing.) Schwinn's practice of offering this style of bicycle as its second-highest models continued until 1978.

The three new models were the Paramount, the Superior, and the New World.
