ACS Brand 10 Hole 1.375 x 24 Right Hand threads Flange style Freewheel.  Made to attach many types of "A" sprocket to the flange to make a freewheel sprocket.

Flange OD is 78 mm or 3.07".  Chrome in color, not the gun metel gray as shown in the pictures with the attached sprockets.

Bolt Circle Pattern:  67 mm or 2.6378"
1.32" from the center, then 72 degrees apart.

This flanged freewheel - sprag clutch allows you to attach a larger sprocket or pulley to make it freewheel.

Stronger, less expensive, and easier to replace than cassette hubs. ACS has set the standard for freewheels for almost 2 decades! Crossfire freewheels are removable with our unique 6-spline tool that fits all sizes. 3 pawls engage 30 steps (every 12 degrees).

ACS # 63816-5000

CLICK HERE to add the 5 mm Hex Head Nylock Nuts.

You also can add one sprocket to each side of the flange giving you a 2 speed.  Use a spring loaded idler to take the slack out of the chain.  This is something you would stop and move the chain by hand to switch the ratio.  You also will need the 25 mm long socket head cap screws and maybe Five 6 mm flat washers used as spacers to keep the sprockets apart so the chain clears.
