Four Aces Cycle Supply is a custom Triumph specialist based in Pacoima, California. These Valley boys ‘worship at the altar of the ribbed fender and peanut tank’, as this Pre-Unit Hot Rod shows. It arrived at the workshop for some minor fixing up; it left as a mix of 1948 Speed Twin and 1950s bobber, with muted colors applied by Rick Grindle. Four Aces’ classy website is a temple of So. Cal. style, and well worth a visit. While you’re there, check the stunning photo retrospective of the Barbarians, a So.Cal. motorcycle gang from the late 50s and early 60s.
