My R088 frameset arrived. It's most definitely full internal cabling. Surprisingly, this frame can also be setup as mechanical. There's a hole for a mechanical FD cable and the RD hole exits through the bottom chain stay. I don't have the most accurate weighing method, but on my luggage scale with RD/FD hangers and cage screws, size 52cm frame comes out to about 780-800g. Uncut fork is about 340g. From what I can see inside the frame, the EPS molded carbon looks clean. The frame and fork uses a P1.0 thread pitch on the thru axles. I didn't weigh the seat post yet (specs say it's about 175g), but it's quite thin and there's a Di2-style battery holder included. The bare UD glossy looks fine, nothing fancy. I'll post photos later.
