This year, the CHUMBA organization will turn 16 years old.  Starting from extremely humble beginnings in the corner of a small bike shop, CHUMBA's story is one that revolves around tremendous personal sacrifice, commitment, and a burning passion to make the best bicycles possible.

As many of you know, the story starts in Anaheim, California, with CHUMBA founder Ted Tanouye, the son of a NASA aerospace engineer.  In the 80s, when suspension mountain bikes were in their infancy, Ted was  known as the kid who received a welding torch from his father as a Christmas present, and then use it on the neighborhood's kids bikes to make some of the first suspension bikes in existence.  Ted went on to graduate from the University of Southern California where he studied mechanical engineering and accounting.

After college, he went on to open one of Southern California's premier high-end bicycle shops, the Bike Beat, in Fullerton, California.  He carried some of the most innovative bikes of the time, including Mantis bikes - which were produced locally by Mountain Bike Action Editor Richard Cunningham.  Ted continued to ride the Fullerton Loop - a trail network put together by MBA's editor and rode every Thursday evening by Ted and crew until this very day.
