A couple additional notes. First, everything was very well faced. Maybe due to that I ordered it as a built bike and that was an advantage, or maybe they just do a nice job. I did pull the bb to replace with a ceramic, and the finish level interior is at least as nice as the photos posted.
The crankset they sent I scoffed at, but its actually ok, 780g w rings, direct mount 3 bolt sram style, 24 mm. I'm not going to use it as I have a carbon sram here with a quarq.
I did have a very minor issue with the seatpost, I had ordered all matching gold anno bolts for everything. The kit for the seatpost came with a gold barrel, and it was set for the oem post and about a half mm larger than tantan's. Fixed it by reaming the post, but the tantan barrel was visually smaller, so not a tolerance thing but an actual difference.
