looks like a Trigon frame, seen them under a bunch of different brand names. I think they had those bikes up on the site before but don’t see the $800 model right now.
It is a generic taiwanese carbon frame.Not trigon though. The quality of these frames are pretty good. However, they come only with a gel coat and no clear PU coat over so when it rains, the bike soaks up a bit of water and has murky white patches.
Other than that, they are pretty well made, wouldn’t pay the asking price though.
