I ordered recently R-086 (aero one from them). Got 820 EUR quoted.
In general, I like geometry and ride feel.
However, the very very big negative for me is the seatpost slipping down. I am pretty much freaked out at any decsent.
Support from Yishun exists, but I am not really sure they can solve an issue.
I will keep you posted if I have luck.

I have an r068d as one of my Chinese frames and have never had a slip. I'm 85kg-ish. I'm using peaty's carbon paste.
Serge_K:
Make sure you torque enough & use carbon paste.
If it's a tolerance thing, then consider using a soda can shim, or some fiberglass cloth.
Also consider greasing the thread of the plug, especially if you've sweated on it. The torque shouldn't go into turning the screw, the torque should go into pushing the expander into the seat post.
Afaik, save for crazy exceptions, "all" seatpost slipping is fixable.

Thanks. I use carbon paste. I have used sandpaper, but not yet tried outside. Bought a threadlocker as the very last option if nothing works. Yishun confirmed the post I have measured is underspec and offered a replacement one. We will see if it works.

Yishun are LightCarbon AFAIK. So unless these are business only models, you should be able to order them.
But it's possible they may be B2B only.

The 3cm spacer stack must be factored in, it throws off the stack/reach ratio. No way around it.
