I just purchased this frame and I'm just starting to build it up. Going to run it rigid with a 1x11 Di2 drivetrain. Seems like few people have this frame - in fact, I have not read anything about it so far. I'm impressed with it on my bike stand; it looks good - I'm excited to ride it. Budget restraints are causing me to build the bike slowly... so it's going to be a while before its ready to test.
