Park Tool Freewheel Remover for Atom/Regina/Splined Zeus

Park Tool offers a full range of tools for bicycle freewheel removal and installation. The FR-4 fits 20-splined tool fittings found on Atom, Regina, splined Zeus, and some Schwinn-approved freewheels. Thin wall construction allows use without removal of cones and locknuts. The 1" hexagonal base can be used in conjunction with a socket, wrench, or bench vise. Heat treated alloy tool steel construction for a lifetime of use. The FR-4 has 20 splines and is approximately 21.6mm in diameter at the widest point. Center bore for axle clearance is 10mm. To determine the type of rear sprocket system you have, find the tool fitting on the sprocket set. Spin the sprockets backwards. If the fitting spins with the cogs, it is a cassette system. If the tool fitting does not spin with the cogs, it is a freewheel system. To determine the type of freewheel tool needed, count the number of splines in the tool fitting. If there are 20 splines, the FR-4 is the correct tool. In addition to the correct tool, you will also need a method of driving it such as the Park Tool FRW-1 wrench, an adjustable wrench, or a 1" socket. Park Tool makes a full line of cassette lockring and freewheel tools to empower you to remove the rear cogs of virtually any bicycle. Here's a selection of tools similar to the FR-4: Since our origins in the back of a bike shop in 1963, it has been Park Tool's sole mission to design and manufacture high-quality tools that empower mechanics and riders of all skill levels to service their bicycles.
