How to Attach a Cable to a Rock Shox Fork

How to Attach a Cable to a Rock Shox Fork
While you are riding your mountain bike off road or on the road you will want to be sure that your cables will function as necessary, but don't hang loose on your bike frame: Be sure that the cables, especially the front brake cable for a fork like a Rock Shox fork, have enough play to enable you to turn the handle bars fully, but are secured to the fork to minimize the chances of catching branches or other objects as you ride along.

Instructions

Difficulty: Moderately Easy

Things You’ll Need:
  • 5mm brake cable
  • 30 to 32 inches of 5mm brake cable housing
  • One zip tie
  • 2x5mm ferrules
  • Cable Housing/Cable Cutters
  • Snips
  • Crimp type cable ends
Step 1
The underside of the front brake lever has a slot in it. The locknut for the brake cable and the adjusting screw also have slots in them. Line these all up. Then pull the front brake lever in all the way. You will see a swivel with a hole in it for the brake cable end to fit into. This will also have a slot in it. Slip the brake cable into the hole and run the brake cable through all of the slots so it is now running out of the end of the brake lever. Give a turn to the adjusting screw so the brake cable won't fall out of the slots.
Step 2
Slip a ferrule onto the end of the brake cable housing and slide the housing onto the brake cable. Run the housing all the way up the cable so it sits into the adjusting screw. Don't worry about the cable being loose right now. That will change later.
Step 3
Slip another ferrule onto the brake cable and seat it on the other end of the brake cable housing. On the back side of the left stanchion of the fork you will see a hole in the top of the caliper housing. This is for the brake cable housing to sit in. Run the brake cable through this hole until the housing sits firmly into it. Now run the brake cable end through the brake cable holder at the end of the brake tensioning arm on the caliper housing. The holder has a 5mm Allen head screw attached to it, so it should be easy to see.
Step 4
As you move the tensioning arm up and pull down on the brake cable, it will give tension to the brake and hold the brake cable and housing in place. Tighten the 5mm screw down to hold the brake tensioning arm in place. Be sure that the brake cable housing is seated firmly at both the adjusting screw on the brake lever and on the disc brake housing. Go back up to the adjusting screw on the brake lever. Screw the locknut out against the adjusting screw, then screw both all the way in. Adjust the brake tension as needed at the tensioning arm on the caliper housing. Clip off the excess brake cable length so that 1.5 inches of it remains. Slip a crimp-able cable cap onto the end of the brake cable an crimp it down in two to three spots on the cap.
Step 5
The last step in this process is to zip tie the brake cable housing to the fork. On the back side of the bridge of the fork you will see four protrusions: two on the upper side and two on the lower side. Position the cable between the upper and lower protrusions and zip tie the cable in place. Snip off the excess end of the zip tie. Be sure that the handle bars can turn freely.

Tips & Warnings

 
Once you have the brake cable tension adjusted correctly, give the wheel a good spin. If you hear the brake calipers rubbing against the disc, bring you bike to a repair shop to have the brake adjusted. The disc could be slightly bent, or the brake caliper housing needs to be aligned properly.
