Crotch Rocket Bicyles

Crotch Rocket Bicyles was started in Santa Barbara, CA in 1983 by Terry Marchiando, who hand made aluminum bicycles locally before offshoring to Taiwan. In 1985, Terry moved the company's address up the road to Goleta and continued there until 1988 ¹⁾.

Data from archive.org, bizapedia and mombat.

Goleta was also home to the perhaps related Crotch Rocket Factory, a motorcycle component company active during the same period. Terry may have been employed there (?):

Marchiando was designing aluminum motorcycle parts and racing motorcycles when he became interested in the new sport. In 1980 he built his brother a mountain bike out of aluminum tubing that lay scattered around his yard. He grew to like the new sport because it “seemed environmentally conducive to this new age we're in.” By 1983 he was making limited quantities of aluminum frame bikes. 1987 Santa Barbara Magazine, archive.org

Although the pic comes from a 1985 Bicycle Guide review, it's likely a 1984 as their 1985 catalog shows XC components.

1987 AL2

Pic from the Nov/Dec 1987 issue of Mountain Bike magazine.

No clues from the pic on components - other than they seem black. By 1987, no one produced a black rear derailleur cage with a black body. Reflection? Photo touchup? Now, all derailleurs seem to be all-black.
