ACS PAWS 4.1 freewheel
This updated version of the ACS Crossfire freewheel allows for the use of a standard 4-prong removal tool without the need to mess with your axle hardware.
It's perfectly safe to install a freewheel on either the fixed or free side on any standard rear track hub. Seriously. Anyone saying otherwise is a kook!
