All options are out of stock
ACS Crossfire components are the parts you need to pull ahead of the pack - precision made from the best materials. Crossfire components are meant for BMX racers and all types of demanding riders.
Before there was "dirt", "flatland", "vert, "street" there was 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 ruled BMX in the 70's, and ACS mags were featured on popular selling bikes.
For those who can't stop grinding their chains, heavy metal reinforcements are here.
All ACS freewheels feature chromoly sprockets with 4 pawls (2 pairs engaging alternately), for quick engagement.
Please Note: ACS 16T - 22T freewheels thread on Standard English hub threads, and remove with the ACS universal removal tool.
All ACS 14T and 15T freewheels thread onto smaller, metric "BMX Flip-Flop" threads.
