Cables and hoses should always enter frame on the opposite side of the headtube than where they are mounted to bars, with enough spare to allow bars to spin at least 180 in case of a crash.
A really neat trick is to use cable shrink wrap or even just electrical tape to wrap pairs of hoses that run from same side of the bar together... keeps things nice and clean and rattle free.
Remember to follow the cable routing on the banshee website FAQ page.
Thanks for the reply. I guess I did a really bad job of wording my original question, though!
I know cables/hoses from the left side of the bar go into the right side of the frame and vice versa. My question is moot now as I figured it out, but I'll reword again in case someone else is wondering (and because I was an English major in college and I need to improve my own writing!)
If you're looking at the frame from the side, should the brake hose or the shifter/dropper cable be in the most forward, closest to the headtube, of the two angled grooves in the port?
I realize after building up the frame that it doesn't matter — both grooves are the same size and there's no functional difference on cable/hose placement between the fore/aft groove.
Thanks again for everyone who tried to help!
