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.
