American Cycle Systems (ACS) is a cycling company that provides performance parts for BMX racing.
This is a niche company for the world of BMX racing. BMX requires components that can hold up to some pretty crazy forces. They need to have all the ruggedness of mountain bike components but be lightweight enough to make tricks possible. BMX drivetrains are geared for high torque and acceleration, which puts wear on the parts that other riding styles don't often see. This means companies like ACS need to make niche products like this, where the dimensions are different, the riding practices are rough, and the competition is high.
