---- ===== Specialized Overview ===== Mike Sinyard started Specialized Bicycle Components in 1974 in Campbell, CA, first importing Cinelli parts and later re-branding Japanese road tires. Complete road bicycles started in 1981. Specialized in 1982 was ground zero for the modern bicycle revolution, when sales exploded by an order of magnitude each year for another 4 years. (([[https://www.amazon.com/Birth-Dirt-Origins-Mountain-Biking/dp/1892495619|The Birth of Dirt by Frank J. Berto]], Berto states that mt. bike sales grew five years in a row by an order of magnitude, starting in 1981. Specialized didn't do **that** well, but they are a $685M sized company as of 2019 [[https://blog.trivelo.co.uk/why-are-there-no-bikes-in-stock/|trivelo]] )) (([[https://mbaction.com/the-history-of-the-stumpjumper/|mbaction]])) (([[https://www.inc.com/magazine/201904/christine-lagorio-chafkin/specialized-bicycle-cycling-private-titans.html|inc.com]]))

Specialized started to produce the Stumpjumper in 1981, making it the first mass-production mountain bike. The first Stumpjumper was produced in Japan and was based on a design for a custom-made bike originally marketed by [[ritchey:start|Tom Ritchey]], Gary Fisher and Charles Kelly. ... The first Stumpjumpers had welded steel frames because the lugged and brazed frames that designer [[lighthouse:start|Tim Neenan]] wanted to use were not available at the time. The original bike had a modified BMX stem and handlebars based on Magura motorcycle handlebars. The bike was equipped with 15-speed Suntour ARX GT gears, originally designed for use on road bikes, and the Stumpjumper also featured Mafac cantilever brakes and a TA Cyclotourist chainset, both designed for touring bikes. ... The bike weighed just under 30 pounds. [[https://en.wikipedia.org/wiki/Specialized_Stumpjumper]]

Today, [[https://www.specialized.com/us/en|Specialized]] is a $685M company with 1,200 employees whose bicycles are mainly manufactured in Taiwan (([[https://blog.trivelo.co.uk/why-are-there-no-bikes-in-stock/]])).

---- ===== 1981 Stumpjumper ===== In November 1981, a batch of 250 Stumpjumpers frames arrived from 3 Rensho ((Specialized used [[https://loosebearings.wordpress.com/2011/02/26/builder-profile-3rensho/|3Rensho]] to build its Allez)), Japan and sold as a complete bike for $750. (([[https://mbaction.com/the-history-of-the-stumpjumper/|mbaction]])) ((It's likely that only 200 Stumjumpers were made in 1981, as no serial numbers > 198 have been recorded.

---- ===== 1986 Rockhopper ===== The Rockhopper was usually a step down and a pound heavier than the Stumpjumper. Full XT components in 1986 show Specialized's commitment to making the best throughout their product line. Shimano Deerhead XT (M700v2 - 1985-86).

And photos are similarly rare.

---- ===== 1989 RockCombo ===== Another early attempt to introduce gravel bikes to the masses. It didn't sell and became another "evolutionary dead end."((Nice phraseology all copied from [[http://classiccycleus.com/home/1989-specialized-rockcombo/]])) SunTour XCD-6000 (1988-89.)

Specialized had the right idea, but nobody wanted the combo. Yet. [[http://classiccycleus.com/home/1989-specialized-rockcombo/|classiccycleus]]

---- ===== 1990 Stumpjumper Epic ===== M-732 (1989 only - but the 1989 Epic has chainstay brakes.) Specialized claims that their titanium Epic debuted in 1990, but reviews from late [[http://mombatbicycles.com/MOMBAT/BikeHistoryPages/Specialized.html|1990]] suggest that titanium came out in 1991.

---- ===== Stumpjumper Identification Guide ===== Early Stumpjumpers are quite rare and many shops and even museums show off 1982 Stumpjumpers as being from 1981.
