Schwinn Overview

Schwinn was the dominant manufacturer of American bicycles since its founding in 1895. After missing the mountain bike boat, it ceased building bikes in the US by 1991¹⁾ and later went bankrupt in 1992. Schwinn was well placed to rebrand some of their existing BMX bikes as being “all terrain” and tried to places them against hand made, expensive mountain bikes. However their early efforts were to simply slap derraileurs on BMX bikes and not design a new bike from the ground up. Their first decent mountain bikes didn't appear until 1985, with their Sierra, High Sierras and Cimarron with triple chainrings.
Some 1982 prices:

• Schwinn King Sting 10: $570
• Ritchey Sierra: $820
• Specialized Stumpjumper: $750
• Univega Alpina Pro: $419

And now you can see why almost no Schwinns were sold and why Univega outsold Specialized by a factor of 5 in 1980s²⁾. Schwinn created what Gary Fisher called “bike shaped objects” ³⁾.

1978 Klunker 5

Klunker? Someone at Schwinn was hip to the haps in Marin. Schwinn dealers weren't, however, and the product dropped like a stone into the quiet pool of obscurity, not even lasting long enough to show up in a Schwinn catalog. Like its namesake, Schwinn Klunkers had to be pushed uphill and wouldn't last a speed run down Repack.

1979 Spitfire 5

After the name “klunker” proved unpopular, a new chainguard was created with a snappier name and once again it failed to even make a catalog. Very few were sold, despite a low price of $120. And a weight of 45 pounds…

1981 King Sting 5

After giving up on klunkers in 1980, Schwinn continues to not get it in 1981. Somehow, perhaps due to their unpopularity and thus rarity, King Sting 5's go for $5000 and up on eBay. Where $500 will get you an early Stumpjumper…

1982 King Sting 10

Now Schwinn sees the light. Decent gearing (40×48 - 14-38) and weight (26 lbs.) Crap components and overpriced, Schwinn fails to capture any market share. Lasted two years.

1982 Sidewinder 10

Nearly the same as a King Sting 10, with cheaper components, if possible. Three year production run.

More popular than the King Sting.

1983 Sierra

Getting there. Schwinn just can't let go of the BMX stem and handlebars. In 1984 it came with a triple crankset. The Sierra model name ran for many years, in many different incarnations.

1984 High Sierra

In 1984 Schwinn switched to a triple crankset and the Ritchey invented bullmoose handlebars.

1985 Cimarron

The Cimarron was fillet brazed! Using top of the line components and an excellent Japanese made frame, Schwinn was trying to recreate the Paramount of mountain bicycles. Too late for Schwinn, however, as Schwinn's race to the bottom of the market pushed margins into the red. Five year production run.

Just swap the handle bars, and it would be good for Repack. And maybe those tires… mombat
