Installing a Freewheel or Cassette

To install a freewheel, follow these steps:

1. Apply grease to the threads on the inside of the freewheel and to those on the hub.

2. Thread the freewheel in a clockwise direction, being careful to make sure that the threads align properly.

3. Thread the freewheel by hand until it begins to tighten.

You can use a chain whip to tighten the freewheel further, although this usually isn’t necessary because riding the bike will tighten it.

To install a cassette, following these steps:

1. Slide the cassette onto the body of the free hub.

Find the one spline on the freehub that is wider than the others, and align it with the same wide spline on the inside of the cassette.

2. Slide any smaller individual cogs onto the hub.

If there are spacers be sure to include them in the proper position.

3. Grease the threads of the lockring and screw it into place on the hub.

4. Attach the freewheel remover to the center of the cassette.

5. Insert the quick-release skewer into the center of the hub, and tighten the nut to hold it in place.

6. Using an adjustable wrench, turn the freewheel remover in a clock­wise direction to tighten.

After you hand-tighten the lockring, you only need to tighten the lockring about five to ten clicks with the tool. Do not overtighten.
