R088 is done. 7.2kg on my heavier 45mm depth carbon wheelset and 6.9kg on my 1100g 30mm depth climbing wheelset. This is with pedals, power meter, bottle cages and built-in computer mount with 34cm drop bars.
Unfortunately I can't ride it due to multiple fires in the Los Angeles, USA area. The air quality right now is s**t...smells like a smokey camp fire. I'll post photos tomorrow. I had to clear out my yard of debris and ash!
FYI - I'm about 173cm and I went with a 52cm frameset.
