Cassette or Freewheel?To determine the type of rear sprocket system, find the tool fitting for your sprocket set. Reverse rotation of sprocket If the fitting rotates with your teeth, it is a cassette system. If the tool fitting does not rotate with your teeth, it is a freewheel system. |
Counting NotchesTo determine the type of freewheel tool you need, count the number of splines or notches and measure the outer diameter of the tool fitting. If there are four notches and the diameter of the mounting part of the tool is about 40mm, the FR-6 is the right tool. |
Professional ToolsIn addition to proper tools, you will also need a method of driving tools such as the Park Tool FRW-1 wrench, monkey wrench, and 1" socket. |
