The frame has finally arrived at home! I weighed all the parts and the frame is rather light, I expected heavier in size 20" in non-SL version: 1858g without the small parts and 1898g with the hardware and the derailleur hanger.
In terms of finishes it is really high-end, the glossy black paint is magnificent, the inside of the frame is perfectly smooth, the ducts are well made, the wheel axle is light (39g) and well finished, ... You will understand that I am very satisfied for the moment!
I made a small decoration with rather sober brushed gold stickers, and I made a protection of the chainstay with 3m 2228 tape, it does not look bad at all and I will try to take some pictures tomorrow.
To sum up, the frame took a little less than 2 months to arrive at my place from the time I ordered, and there were 2 weeks of delivery (shipped November 19 and received today).
