Build is finished - pictures tomorrow.
1x10, Shimano XT 786 mech, Sunrace 11-42 casette, Microshift shifter, Sram chain. Works like a dream...
(and the XT mech with ShadowPlus is tight and quiet - but takes some effort and then a bit more for shifting. Very well articulated, no ghost shifts, no hesitation, no chain slap... just works).
Will be taking it tomorrow for a longer spin, picked it up after sunset.
