Cyclus Tools freewheel remover tool to be used with 3/8" ratchet wrench only. 2 notches, approx. 25mm diameter (outside to outside) - e.g. compatible with 4/5/6-speed freewheels from Atom, Maillard, Regina and Suntour. Always use a skewer or axle nut to hold remover firmly in place, otherwise the notches could be damaged.
