Anyone who has built the frame already, any tips for getting the hydraulic brake cables through the integrated handlebar?

I'm about to throw them at the wall 

I'll take some once I get it onto the workstand

Just got mine delivered. XL and from what I understand, it's able to take 46T.

I'll share pictures as I build, but here's the frame straight out the box

Can anyone suggest a strong integrated out front computer mount for the grt?

Most I've found are more for the road and I'm concerned they won't last.
