9. Converting to single speed
Convert to single speed: Your rear wheel most probably has some sort of gearing cogs attached to it. There are two main types:
- The older design is referred to as the freewheel block: this is screwed on as one block. The sprockets cannot be taken apart
- Freewheel cassette: The modern version, in which the freehub and sprockets can be taken apart
Our rear wheel has a freewheel block. The procedure to remove this is described below:
- In order to remove this, we need to use a lock ring remover.
- Remove the wheel nut and insert the vertically grooved end of the lock ring remover into the axle, and ensure that is sitting well
- Now, unscrew the lock ring remover anti-clockwise
- Use a vice to clamp the wheel - it is very possible that the lock ring has fastened extremely tightly. You really do not want to bend the spokes or the rim during this procedure
- Once the block has been removed, you can screw on a single speed freewheel. These usually have about 14 to 18 teeth.
- Now mount the rear wheel and give it a spin. Carefully grip the freewheel and check that the wheel still moves. There should be no screeches, squeaks etc. Just the tick tick of the freewheel
