Bottom Bracket, Cranks, Chainline

I installed an SRAM PF30 BB and Eagle GX 32t crankset.

The cups pressed in without issue. I pressed drive side first, then non-drive. After drive side was pressed, I put the spindle through and checked for concentricity with the shell. Pleased to say it *looked* spot on. I removed the spindle/crank and pressed the non-drive cup. The spindle fit straight through both bearings quite easily.
 
Cups were pressed in dry. I guess i'll see if there's any creaking.
I used the thicker 3mm spacer included with the cranks on the drive side and no spacer on the non-drive side. This yielded a 51mm chainline (49.5 + 1/2 thickness of 3mm chainring). I'll see how this chainline shifts and adjust if necessary.

All this to say, I don't have any concerns about the bottom bracket cranks install on this frame.

Internal Cable Routing
Not an exciting topic, but i'll cover it regardless.
Airwolf helpfully included "trace lines" that are taped off to facilitate easier internal cable routing.
This build needed the following internal routes:

• Rear Derailleur
• Rear Brake Caliper

No dropper post, no front derailleur

Rear Brake - Shimano SLX disc, BH-90 lines
Ran the line from the caliper end up to the lever
Tried taping the trace line to the brake line and pulling it through the frame. Even though it was only one layer of electrical tape wrap, this proved too thick to pass through the chainstay.
So I pulled out the trace line and force-fed the brake line through the chainstay - it just barely fit through. The chainstay necks down making cable routing really tight. Once through the chainstay the line routed above the bottom bracket shell and had a straight shot up the downtube. I used tweezers to fish the end of the line out of the port hole near the headtube.

Rear Derailleur - SRAM GX
There is a removable cover under the bottom bracket shell that is secured with a single screw. The cable ports for the rear mech have housing stops implying you should terminate the cable housing at the ports and only run the shift cable itself internally. I opted to drill out the stops in the port covers so the full shift cable would pass through. Starting at the BB access, I ran the shift cable up the downtube and to the shifter, then fished the other end down the chainstay to the rear mech. I didn't want the cable friction riding along the BB cable guide, so instead ran housing the full length.
