Wont fit a GP5000 35C, and geometry is ~SL8 so also lower stack than i'd like, and feels significantly overpriced for the specs and weight, but it looks like it's an actual brand, so, fair game i guess. Wouldn't spend that kind of money on a frame if i weren't in one of their jurisdictions, but it's a nice looking aero bike. May be a good pick for lighter Australians, for eg.

Came up on my aliexpress feed.

I've seen a China Rides video about this brand.

It is Winow WR054

I've been riding it for more than a year. The frame is very well made, but overall setup is simply too heavy. The geometry is similar to the Factor One, with a steep seat tube angle that puts the saddle in a very forward position. I described all of this in the Winow thread.
