This is a 20 tooth rear freewheel - replacement for the OCC Schwinn Stingray Chopper bicycle

This 22 Tooth is required if you want to run a single speed jackshaft using PedalChopper Transmission system...  as  it matches up to pre-determined gearing ratios.

 I use the ACS Crossfire Freewheel on my builds as it accepts either multi-speed or single speed chain. In this way, it does not matter if my [Crank] or Front Sprocket is single speed or multi speed, it will accept whatever chain you are running. I like to avoid using the chain pulley tensioner from motorized bicycle kits on the motor drive side if at all possible.  If you want to equal the chains out so they are even (without a chain tensioner) you may be able to accomplish this by adding or reducing teeth on your bicycle crank side freewheel.

DOES NOT REMOVE STINGRAY FREEWHEEL - THERE IS NO TOOL FOR REMOVING STINGRAY FREEWHEEL.   This is a special removal tool for removing the ACS Crossfire FREEWHEEL that we recommend on this site.  NO OTHER FREEWHEEL TOOL WILL WORK ON THIS  style Freewheel.  I only use the ACS Crossfire Freewheel on my builds as it accepts either multi-speed or single speed chain. 

THIS IS THE 5 SPEED FREEWHEEL I USE ON MY 5 SPEED RTRO-FIT PROJECTS
