TanTan TT-X38 Build

[Frank]

In my case the distance of the inner mounting surfaces of the fork is even 103,3mm. I glued in a 1mm spacer on each side and so far there is no problem. What is important is that 1. the wheel is centered when the thru axle is torqued properly and 2. that the outer surfaces of the wheel/hub axle sit flat on the inner mounting surfaces of the fork (i.e. no gap at any point).

so the gap between 2 dropouts you made it to be 102mm permanently rather than force squeeze a lil to be 100mm?

i was using thruaxle L125-TL14  (101mm gap) when i got the play.
i happen to have L121-TL17 to test(attached pic), and the wobble reduced as i somewhat overtighten a bit (till the wheel stop wobbling, has a lil resistance to rotate).based on calc, around 99.67mm.

and upon inspection, this is what it looks on my dropout of nut side. 
kinda uneven. TanTan is not really responsive on this issue. 
should the nut fully exposed, or should be covered by carbon?

i think i need to find thruaxle with solid part lenght 109-110mm (the left dropout seemed to be around 9.6mm thickness

I reduced the gap between the dropouts from 103.3mm to 101.3mm by adding a 1mm washer on each side and the remaining 1.3mm is "squeezed" by tightening the thru axle.
