Chilcotin vs. Race Face Atlas crankset spacers configuration

[BikeBert]

I will be running 2 chain rings + rockring and 9sp cassette.
From the other thread I know the proper Bottom Bracket black 2.5mm spacers configuration is as follows:



*6C - 2.5mm BB Cup Spacer [black]

If this is with our build kit, the left Raceface BB cup has no spacer; the right BB cup uses ONE of the 2.5mm BB cup spacers.

Cheers!

However, I have problems with white 1mm crackset spacers.
What is the optimal chain line for my application [2 x 9sp] and spacers configuration?

OK, so I went with 51mm chain line and it seems to be optimal
