So I'm building my new frame (2012) and things are going fine until I get around to the front derailleur cable/housing. The frame has internal routing and I set up the rear no problem using the supplied guide sleeve. However on the other side, there is no internal cable stop so I figure it must be fully cabled; sure enough I can see cable stop looking up through an aperture just behind the BB shell. So after a good frustrating while trying to get the cable and housing through the frame I finally manage to get the stars aligned but I realize there is absolutely no way the housing can make a 90 degree turn into the stop with only 3/4 inch wiggle room. I've been searching online and I see lots of older Redlines have the front derailleur cable routed along the down-tube. If this is the case, why bother making a giant hole in the frame? I'm going crazy here so any help greatly appreciated.
