Unlike its progenitors, the Klunker proved incapable of withstanding hard off-road use, and after an unsuccessful attempt to reintroduce the model as the Spitfire 5, it was dropped from production. Another problem was Schwinn’s failure to design and market its bicycles to specific, identifiable buyers, especially the growing number of cyclists interested in road racing or touring. Instead, most Schwinn derailleur bikes were marketed to the general leisure market, equipped with heavy “old timer” accessories such as kickstands that cycling aficionados had long since abandoned. More and more cyclists, especially younger buyers, schwinn electric bike began to insist on stronger steel alloys (which allowed for lighter frames), responsive frame geometry, aluminum components, advanced derailleur shifting, and multiple gears.[8][30] When they failed to find what they wanted at Schwinn, they went elsewhere. While the Paramount still sold in limited numbers to this market, the model’s customer base began to age, changing from primarily bike racers to older, wealthier riders looking for the ultimate bicycle. Schwinn sold an impressive 1.5 million bicycles in 1974, but would pay the price for failing to keep up with new developments in bicycle technology and buying trends.
This in turn led to further inroads by domestic and foreign competitors. Faced with a downward sales spiral, Schwinn went into bankruptcy in 1992.[59] The company and name were bought by the Zell/Chilmark Fund, an investment group, in 1993. Zell moved Schwinn’s corporate headquarters to Boulder, Colorado.
The wheel rims were likewise robust, chromed, stamped steel with a unique profile designed to hold the tire bead securely, even if pressure were low or lost. By 1975, bicycle customers interested in medium-priced road and touring bicycles had largely gravitated towards Japanese or European brands. In reality, mass-market French manufacturers such as Peugeot were not infrequently criticized for material and assembly quality — as well as stagnant technology — in their low- and mid-level product lines. Nevertheless, Peugeot proudly advertised its victorious racing heritage at every opportunity. By 1979, even the Paramount had been passed, technologically speaking, by a new generation of American as well as foreign custom bicycle manufacturers.
By 1960, annual sales had reached just 4.4 million.[10] Nevertheless, Schwinn’s share of the market was increasing, and would reach in excess of 1 million bicycles per year by the end of the decade. By the mid-1970s, competition from lightweight and feature-rich imported bikes was making strong inroads in the budget-priced and beginners’ market. While Schwinn’s popular lines were far more durable than the budget bikes, they were also far heavier and more expensive, and parents were realizing that most of the budget bikes would outlast most kids’ interest in bicycling. Although the Varsity and Continental series would still be produced in large numbers into the 1980s, even Schwinn recognized the growing market in young adults and environmentally-oriented purchasers, devoting the bulk of their marketing to lighter models intended to pull sales back from the imports. In late 1997, Questor Partners Fund, led by Jay Alix and Dan Lufkin, purchased Schwinn Bicycles. Questor/Schwinn later purchased GT Bicycles in 1998 for $8 a share in cash, roughly $80 million.
Often times you will see road bike tires labeled something like; 700×25. The first number (in this case, 700) indicates the diameter of the tire in millimeters and is fairly standard in the category. The second number (25) shows the width of the actual rubber tire in millimeters and is more likely to vary across individual bikes in the category.
The new company produced a series of well-regarded mountain bikes bearing the Schwinn name, called the Homegrown series.[62] In 2001, Schwinn/GT declared bankruptcy. In the past road bikes were almost uniformly designed to have just one form of brakes, and those were rim brakes. Since then, disc brakes, which were originally seen in the mountain biking category, have made their way into the road scene, creating a great debate among road cyclists.
By the late 1970s, a new bicycle sport begun by enthusiasts in Northern California had grown into a new type of all-terrain bicycle, the mountain bike. Mountain bikes were originally based on Schwinn balloon-tired cruiser bicycles fitted with derailleur gears and called “Klunkers”. A few participants began designing and schwinn road bike building small numbers of mountain bikes with frames made out of modern butted chrome-molybdenum alloy steel. Using the standard electro-forged cantilever frame, and fitted with five-speed derailleur gears and knobby tires, the Klunker 5 was never heavily marketed, and was not even listed in the Schwinn product catalog.
