Giant Tcr advanced internal cable help-

I am building up a 2013 Giant TCR Advanced and having a hard time running the cables through the frame, I don’t have much experience doing this so maybe there is a simple way, but you only have a hole slightly larger than the cable and no internal guide.
I tried putting the frame vertical in the stand on a slight angle so when I feed the cable in it will drop towards the hole but no luck.

Thoughts and ideas are appreciated.

don’t have specific advice for that frame, but I’ve heard people attach (not how, maybe tape) dental floss to the end of the cable, use vacuum cleaner to suck floss through frame, then pull cable through. Other method is to run stiff wire through the frame (straightened coathanger works well), slide some thin cable guide over the wire and through the exit ports (don’t use normal cable housing, somehting lightweight, I use thin garden reticulation piping, google 4mm drip line), remove wire, insert cable through guide, remove guide.

I just built up a 2012 tcr advanced sl, so I am not sure if it the same, but mine had black thin cable guides you could install and then run the cable through them. There is a plastic piece below the bottom bracket that is removeable (one 4mm or 5mm hex screw) which gives you a larger opening to be able to pull the cables. What I did is I took a long uncut cable, strung the thin cable guide on it, and than measured about how long the run was from the port on the downtube to the opening under the BB. I pushed about that much cable through and then just fished around with thin needle nose pliers and a flashlight until I could find the cable end and pull it through. The guide was already installed for the rear brake cable so I am not sure what the procedure would be there. One word of caution, if your frame has the same plastic cable plate under the BB, be very careful not to overtorque the hex screw when you put it back it. I did and the threaded insert in the frame came lose and needs to be expoxied back into the frame. String or finishing line and a vacuum also does the trick, done that before.

Thanks, I’ll give all those a try.

If you use a magnet at the point where the cable comes out of the frame, it should attach to it quite easily. I started from the bottom of the top tube then rotated it up. It only works on carbon frames though!
