ACS

Over 30 years ago, aerospace engineers Charles Stephens and Robert Hanson founded ACS and developed, designed and manufactured some of the first high-end BMX components. ACS alloy hubs dominated BMX in the 70s, and ACS mags were found on popular retail bikes. ACS pioneered specialty components needed by the pros like the ACS rotor, RL hub, 100psi tires, and BOA brakes. ACS also developed and produced 5 models of skateboard axles at this time, covering all specialty disciplines.
