I'm looking at getting an endurance frame as a relaxed road upgrade from my gravel bike and have been eyeing the YFR066 by Airwolf. https://airwolfcarbonbike.com/product/yfr066-airwolf-carbon-bike-frame-700c-disc-brake-road-carbon-bicycle-frame-roadbike-frame-carbon-road-disc/

Any reviews on this brand or recommendations for another frame, before I pull the trigger on 11.11 deals?
Frame is about $600, but I am willing to spend $750, if that amount will be enough to get me better quality.

Any help here is appreciated!
Note, I plan on purchasing on the di2 groupset from Merlin or aliexpress and already purchased a yuanan wheelset from Leon, who posts here.

I unboxed the frame which had received about 3 weeks ago..

Those are my impressions

1. Paint quality is good. I worried about the actual color, but it looks pretty good.

2. finishing around mounting part is not perfect. But for me it is okay 'cause those part will be covered with bottle holders and bags.

3. Controversal down tube storage is also looks good. It felt sturdy when I held and shaked it by hand. I will test it with a bidon with full water later.

4. I didn't order the handlebar with the frame to use standard handlebar, so had ordered stem and spacers separtely. It seems not matched well with the basic head tube kit of the frame and it makes me worried...

Assembly will be done by myself, so it will take some time(hope to finish in december).

they don't mention the distance in drops, but 16 degrees flare means, typically, 7-8 centimeters.
They seem to be a copy of (a copy of) Syncros Creston handlebar.
