So i want to take a 2x force crank off a tri bike that has etap 12 speed. I want to put it on my 2018 giant tcx advanced sx 1x cyclocross bike (apex 1) set up for 1x. I presume there is a dub bb to fit the frame, but would spindle length be the same, and could chainline be adjusted?

AFAIK there is only one spindle length for Force/Red DUB cranks. Giants use BB86 IIRC, so you would just get SRAM's BB86 DUB cups...or you could get flanged direct press-in bearings from WheelsMfg or something. The Force crank uses the removable 4-bolt spider and can be converted between 2x and 1x just with chainring swaps. The X-Sync Road chanrings are already offset to address chainline issues.

It’s not necessarily dub, could also be GXP

Unless the tri/tt is a Trek Speed Concept or has an Italian threaded BB, it’s unlikely that the Force crankset is GXP.
