I'm building a Pos-X that I converted to thru-axel. I also stripped the paint and polished the frame. I have not been able to get any SRAM cranksets (170mm) to work without being crazy close to the non drive side chainstay. I used SRAM GXP BB and and a Hope GXP with a 10spd Force, Force 1 and Rival 1 cranks. The Rival one has a pretty wide Q-fatcor. I've heard of similar issues with FSA cranks as well. I ended up using a Shimano CX50 crankset and it clears just fine. Hope to get it cabled and fork cut down soon. I'm also going 1x and 650b.
Btw, the rear TA is definitely a 12mm x 163mm with a thread pitch of 1.5.
