The front fork of a Diamondback BMX Assault bike is an essential component, as it allows the rider to turn fluidly, which is critical in BMX style riding. The front fork connects the front tire to the headset, which is what turns the front tire to steer the bike in a desired direction. Over time, due to the rugged nature of BMX riding, the headset components within the neck of the front fork can become damaged, and the fork will need to be removed to perform maintenance.

Skill level:

Things you need

  • Spanner wrench

  1. 1

    Take off the front tire. Use a socket wrench to remove the front axle bolt by turning counterclockwise. Pull the tire out of the front fork.

  2. 2

    Remove the front brake caliper if you have a front brake installed. Unscrew the caliper using a screwdriver, then pull the brake off of the front fork.

  3. 3

    Loosen the handlebar ring---the threaded hexagonal race just above the handlebar stem---with a spanner wrench and turn counterclockwise. Then pull out the handlebar headset.

  4. 4

    Remove the washers and spacers from the upper steering column. Place your hand underneath the fork neck, then remove the threaded race from the top of the steering column, using the spanner wrench.

  5. 5

    Pull the front fork off of the bike, and you'll be ready to replace or make your desired modifications.

Tips and warnings

  • Always ensure that you pay attention to the location and orientation of parts as you remove the fork. These parts are small and need to be precisely realigned for the steering mechanism to operate at an optimal performance level.
