on America's streets and neighborhoods, many young riders would accept nothing else, and sales took off. In the December 1963 Schwinn Reporter, Schwinn announced the arrival of the Deluxe Sting-Ray. This model included Fenders, white-wall tires, and a padded Solo polo seat. In July 1964, Schwinn announced the arrival of the Super Deluxe Sting-Ray. This model included a front spring-fork, a new sleeker Sting-Ray banana seat, and a Person's Hi-loop Sissy bar. The Super Deluxe also gave the rider a choice of White wall tires or the new Yellow oval rear Slik tire paired with a front black wall Westwind tire. By 1965, a host of American and foreign manufacturers were offering their own version of the Sting-Ray. The Ten Speed A growing number of US teens and young adults were purchasing imported European sport racing or sport touring bicycles, many fitted with multiple derailleur-shifted gears. Schwinn decided to meet the challenge by developing two lines of sport or road 'racer' bicycles. One was already in the catalog — the limited production Paramount series. As always, the Paramount spared no expense; the bicycles were given high-quality lightweight lugged steel frames using double-butted tubes of Reynolds 531 and fitted with quality European components including Campagnolo derailleurs, hubs, and gears. The Paramount series had limited production numbers, making vintage examples quite rare today. Starting in 1960, for the rest of the market, Schwinn offered the Schwinn Varsity, Continental, and LeTour -- now equipped as multi-geared sport bikes (10-speeds), and designed to imitate the style of the new narrow-tired 'racing' and sport bikes from Europe, though not their performance. The 1960 Varsity was introduced as an 8-speed bike, but in mid-1961 was upgraded to 10 speeds. Other road bikes were introduced by Schwinn in the early and mid 1960s, such as the Superior, Sierra, and Super Continental, but these were only produced for a few years. The Varsity and Continental sold in large numbers through the 1960s and early 1970s, becoming Scwhinn's leading models. The major difference between the two models was the use of a tubular front fork on the Continental -- both bikes used the same frame design, a lugless, steel unit, using Schwinn's standard Ashtabula cranksets and welded in such a way that the joints were smoothly filled (similar to the joints in 21st-century composite frames). The wheel rims were likewise robust, chromed, stamped steel with a unique profile designed
