Fits Shimano®, Sachs Aris®, and Sun Race® freewheels. Heat treated alloy tool steel, one inch base fits wrench or bench vise. Thin wall construction allows use without removal of cones and locknuts.
(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.)
