Front Derailleur Cabling
 
You know how the cable for the FD goes through a internal cable routing that goes through the BB from a hole at the bottom of frame? I was wondering, is it possible to do the cable routing without removing the crank?

Should be.

May I ask what tools should I be using and what process is needed?

Cable cutters/snips to cut cables and cable housing

Pliers to pull the cable tight when securing the cable to the front derailleur

Electrical tape and scissors if you are routing under the bar tape

Don't think you understood what my question was. Not talking about cabling it from scratch. It's already cabled. For most modern carbon frame, there's a hole right underneath the Bottom Bracket area where you can put the cable through and it comes back up right behind the seat tube. I was just wondering, is it possible to do that internal cable routing without removing my crankset.

Yes, you can do it without removing your crankset.

Why would you need to remove the crank?
Poke around and find the hole...that's all.

That works better with your crank in place.

Just want to confirm if I can do that before I start removing the cable attached to the rear derailleur.

Have you really looked at the current setup on your bike? There is tiny hole in the bottom of most BBs for drainage, and also a plastic guide piece that might go up through the frame, then come out behind the BB between the space behind the tube and wheel itself.

Follow the current setup, bikes are different, but mine has a plastic adapter that attached under the BB, the cables go under the BB that up behind the seat tube in the space between the tire/wheel and seat tube to then route to the FD.
