I ordered a vb-r-168 frame this week with custom paint light metallic silver.
Size 58cm, my saddle height is 79cm.. I had doubts between 56 or 58, but my current bike has stack 586 and I also use spacers, so I prefer to go with 58. Also, I think it would be too much exposed seatpost in size 56 (only 496mm of seattube).

Chris told me that the frame is in stock and he is arranging for the paint, 10-14 days. Will see the times .

Thanks all for sharing your experiences, amazing info!
