 Diamond Back Bicycles was founded as a BMX brand in 1977 by Western States Imports (WSI) in Newbury Park, California, by Mitchell M. Weiner and Junya (Cozy) Yamakoshi ((who left WSI in 1986 to start [[http://www.parkpre.com/history.htm|ParkPre Mountain Bike]] [[https://www.pacelinebikes.com/blog/the-men-who-brought-japanese-bicycles-to-the-bike-boom-era/|pacelinebikes]])).  WSI also sold road bikes under the Centurion brand.
