Many of the common 3-lug sprockets are made for 1/8" chain -- wider than the chain used with derailer gearing. The wider chain can be used with thin chainwheels made for use with derailers, though special track chainwheels have teeth that are both taller and wider, and allow the chain to become looser before it could fall off. 3-lug sprockets for derailer chain are sold, stamped with raised sections around the hole so they fit the hub the same way as thicker sprockets. With the narrower sprockets, use chain made for a 7-speed or 8-speed derailer system.

The sprocket of most internal-gear hubs is held in position by a spring circlip (snap ring). The circlip can be pried off with a thin flat-blade screwdriver, and the sprocket can then be lifted off. Most sprockets made for this system (including those shown above) are "dished" so you can adjust the chainline by flipping the sprocket over. The circlip snaps on, also most easily by levering it into position with a flat-blade screwdriver. Some hubs will accept a smaller sprocket dished outward than inward, due to interference problems. Some hubs, have one or two spacer washers in addition to the sprocket. Changing the order in which the spacer washer(s) and sprocket are installed on the hub can adjust the chainline.
