---- ===== Kashiwa ===== Kashiwa produced Japan's first mountain bike for sale in Japan (([[araya:start|Araya]] claims to be first, debuting in late 1982. Kashiwa sold first, with magazine reviews being printed as early as June 1982 and prototypes being available in late 1981. Araya certainly produced many orders of magnitude more MTBs than 3Rensho/Kashiwa.)) , after helping to birth Specialized's Stumpjumper in 1980 and 1981. \\ Kashiwa was a spinoff from [[3rensho:start|3Rensho]] ((Often pronounced San Rensho, for "three wins", or "trifecta", both of which google translate gives for articles about 3Rensho.)) who was contracted by Mike Sinyard, the founder of Specialized, to create a cheap MTB. Although the brand's lifespan was a very short two years, they had a foundational place in the formation of the Asian MTB industry. Their bikes supply the most solid evidence of the bridge between 3Rensho and the [[special:start|Specialized]] Stumpjumper. 3Rensho was at the vanguard of the tsunami of MTBs which came in the next few months, supplied by [[araya:start|Araya]], [[miyata:start|Miyata]], [[maruishi:start|Maruishi]], [[hodaka:start|Hodaka]], [[fuji:start|Fuji]], [[focus:start|Focus]]((Focus was an Araya managed brand, in a similar position as Kashiwa was to 3Rensho.)), [[kuwahara:start|Kuwahara]], [[panasonic:start|Panasonic]], [[sekine:start|Sekine]], [[shogun:start|Shogun]], [[marukin:start|Marukin]], [[bridgestone:start|Bridgestone]] and [[toyo:start|Toyo]]. This list does not include American/Canadian brands with Japanese sounding names such as [[nishiki:start|Nishiki]], [[lotus:start|Lotus]], [[sanwa:start|Sanwa]], [[sekai:start|Sekai]], [[sr:start|SR]], [[kobe:start|Kobe]], [[mikado:start|Mikado]], [[takara:start|Takara]], and [[univega:start|Univega]]((Early Univegas were made by [[miyata:start|Miyata]] and [[araya:start|Araya]].)). \\

Mike Sinyard, president of Specialized, purchased two Ritchie's handmade MTBs in 1980 and asked Yoshi Konno (of 3Rensho), who had won three consecutive American bicycle shows, to create a prototype MTB for sale to the public in the fall of 1980. 3Rensho were previously linked to Specialized and had provided them high-end road bikes on an OEM basis. Konno Yoshi brought the Ritchie MTB home with him and told the staff of Sanrensho that he was going to make a prototype of a bike like this. When a staff member from Sanrensho rode an MTB for the first time, he thought it was a very heavy bike to ride. Cambio Workshop blog, [[https://ameblo.jp/cambiokoubou/entry-12694611767.html]]

3Rensho prototyped the first [[special:start|Specialized]] Stumpjumper in early 1981, which was eventually was manufactured by Toyo who shipped Stumpjumpers the US by November 1981. Given an early taste of the happenings in Marin, 3Rensho tried making their own MTBs and found production to be difficult, requiring non standard lengths and widths of tubing, combined with newer, more expensive components. As 3Rensho was known for fine custom work on [[https://en.wikipedia.org/wiki/Keirin|Keirin]] racing bikes, they farmed this new type of bike with partner [[maruishi:start|Maruishi]] and named the brand [[https://en.wikipedia.org/wiki/Kashiwa|Kashiwa]], after 3Rensho's home city, which borders Tokyo. Kashiwa only sold for two years in the Japanese market.
