Schwinn advertisements and catalogs of the past provide a colorful, fun and informative history of vintage Schwinn models.Above are links categorized by decade which document visually the images of Schwinn bicycles as far back as 1895.The extra thickness of the fillet also provides strength, and its smooth contour distributes stresses evenly.(For additional strength Schwinn also brazed steel sleeves into the interior of its frame tubes at the joints.) Fillet-brazed bicycle frames are strong and have a neat and clean appearance, but they are uncommon because of the additional craftsmanship required.We offer the full range of quality bikes at affordable prices!26” MTB, 29“ MTB, road bikes, commuter bikes, kids bikes.Lugged bicycle frames, for example, are now manufactured by automated machines.
Some models had a rear "spoon" brake; most had a bell to keep horses from being spooked.
Fillet brazing involves building up brass filler metal in a smooth "fillet" around joints.
(See illustration below) In this method of bicycle frame construction, "mitering" or cutting the tube ends so that they fit together precisely is critical so that capillary action will draw the molten filler into gaps for a strong joint.
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.
