| ===== Early Mountain Bikes ===== | |
| In 1977 Joe Breeze, Gary Fisher and Charles Kelley started to build the first modern mountain bicycles, defined by their gearing, light weight, strength, and fat tires. Designed to go fast both up and down steep dirt trails. As soon as people saw the possibilities, innovation exploded outwards from Marin around the world. The early origins, from geared clunkers in Marin ([[http://www.clunkers.net/|1974]]) to the Breezer ([[https://americanhistory.si.edu/collections/search/object/nmah_1419571|1977]]) to the Stumpjumper ([[https://www.amazon.com/exec/obidos/ASIN/1891369636/breakawaybooks|1981]]) are well documented(([[https://www.amazon.com/Birth-Dirt-Origins-Mountain-Biking/dp/1892495619|The Birth of Dirt (3rd ed.)]] by Frank J. Berto )). What isn't as well known are the nearly 100 builders during this early period creating their own species of mountain bikes. From 1980, mountain bike sales figures grew by an order of magnitude each year from 300 bikes in 1980 to an astounding 5,000,000 in 1985(([[https://www.amazon.com/Birth-Dirt-Origins-Mountain-Biking/dp/1892495619|The Birth of Dirt (3rd ed.)]] by Frank J. Berto, pages 12 & 83 )). By 1984 every major manufacturer was making a mountain bike and there were over 100 frame builders creating very different designs. | |
| | |
| Most of these have been forgotten. This is an attempt to make a timeline of ALL manufacturers and models of mountain bikes from 1977 -> 1984. Some small builders with less than a dozen frames to their name have had huge influences. | |
| | |
| Borrowing from Frank J. Berto's definition of a "Mountain Bike." (([[https://www.amazon.com/Birth-Dirt-Origins-Mountain-Biking/dp/1892495619|The Birth of Dirt (3rd ed.)]] by Frank J. Berto, page 26 )), a mt. bike must: | |
| | |
| * support tires > 2" | |
| * designed to be used off road | |
| * have low derailleur gearing ((A low gear of 1:1 would be a good start with 26" tires. Some examples: | |
| - Breezer Series I: 32 front x 26 rear. Not so good on a 38 pound bike. This is the same as 3rd gear on a 1979 Ritchey. | |
| - 1979 Ritchey: 28 front x 32 rear. Good. | |
| - Typical 1979 road racing bike: 44 inner x 18 rear, 700c tires. And people wondered why mountain bikes became so popular? | |
| - 1981 Schwinn King Sting 5: 40 front x 28 rear. Not a mountain bike. | |
| - 1982 Specialized Stumpjumper5: 26 front x 28 rear. Good. | |
| - 1982 Schwinn King Sting 10: 40x48 front by 14-38 rear. Schwinn is getting there. | |
| - 2021 Mt. Bikes: 34 single front x 52 rear. Super low. And generally heavier than any old-school Ritchey. | |
| )) | |
| * good, non-coaster brakes | |
| * flat handle bars ((Obviously there are some exemptions. See [[cc:start|Cunningham]] for example. However arbitrary, some filtering is needed.)) | |
| * have a Marin pedigree or connection | |
| * be less than 40 pounds ((What about e-bikes? The [[https://www.trekbikes.com/international/en_IN_TL/bikes/mountain-bikes/electric-mountain-bikes/powerfly/powerfly-long-travel/powerfly-lt-97-plus/p/24819/|Trek Powerfly 9.7]] weighs 51.5 pounds - with a carbon fiber frame...)) | |

| The Specialized Stumpjumper was the inflection point, where sales became exponential. Remarkably, the Stumpjumper wasn't even close to being the most popular mountain bike in any year that it sold. This title should go to the Univega Alpina, which consistently outsold Specialized, by a factor of 2->5 (([[https://www.amazon.com/Birth-Dirt-Origins-Mountain-Biking/dp/1892495619|The Birth of Dirt (3rd ed.)]] by Frank J. Berto )). Specialized wasn't the first mass produced off-road bicycle, as that title can go to both the Lawwill-Knight Pro Cruiser, and the Schwinn 5 speeds off-road cruisers. However, those cheap mass produced bikes were either too heavy, lacked decent brakes or gearing and couldn't be reliably used on rough terrain. The Stumpjumper was the first well designed and mass produced mt. bike and should be standard to rate all others of its day. It's entry point into the market in November 1981 marks an explosion of new bicycle designs and world wide adoption. The resistance from established road bicycle makers to embrace the new bikes, which the world had been waiting for, enabled hundreds of smaller builders to flourish and eventually dominate the entire bicycle market. | |

| Many early makers came from a background of BMX or cruiser designs, which had already embraced the fat-tire philosophy. Many are included in the timeline below if they're evolutionary significant, even if they aren't strong and light enough to be ridden down Repack. There were plenty of capable off road bicycles before 1970 which satisfied the mt. bike definition. For example, French touring and cyclo-velo bikes from 1930 -> 1960 had wide tires, short gearing, sometimes under 20 pounds and were quite strong. Some had front suspension and disk brakes. But they never became popular and were evolutionary dead ends. It took the crucible of the Repack races to create the **//movement//**. | |
