The FR-7 Freewheel Remover is specifically designed for Falcon® brand freewheels. The shape of the FR-7 looks similar to the FR-1 (for Shimano® , Sun Race® , Sachs® and similar freewheels). The FR-7, however, is made slightly larger to fit the slightly larger splined pattern of the Falcon® Freewheel. To make it easy to distinguish between the two removers, the FR-7 has a silver-colored plating. The slightly smaller FR-1 is black.
