Removing The Fork

• 1). Loosen the binder bolts on the stem and headset cap. Remove the stem from the steerer tube.
  
  
• 2). Remove the front wheel from the fork. If the fork is set up for a disk-brake system, remove the brake from the bracket. If it is set up for in-line brakes, remove the brake arms from the posts.
  
  
• 3). Pull the fork out of the head-tube.
  
  
• 4). Use a crown-race remover to remove the headset race from the crown of the fork. Set it aside.
  
  
• 5). If you are installing a new headset with the new fork, use a headset cup remover to detach the headset cups from the head-tube.
  
  

Installing The Fork

• 1). Use a crown-race setter to attach the headset race to the new fork.
  
  
• 2). If installing a new headset, use a headset cup setter to attach the new headset cups to the head-tube.
  
  
• 3). Measure the new fork against the old one, and cut the steerer-tube to the appropriate height. If you leave more height, you must use more headset spacers. Attach the star-nut with a star-nut setter and hammer.
  
  
• 4). Slide the new fork into the head-tube with any necessary headset bearings in place.
  
  
• 5). Slide any necessary spacers onto the steerer tube beneath or above the stem. Tighten the stem compression bolts and headset cap.
  
  
• 6). Attach the wheel to the fork dropouts. If your new fork uses a disk brake caliper, install it to the correct mounting bracket. If using in-line brakes, attach them to the correct brake-arm posts and adjust them for the height of the rim.
