It’s an open mold tideace fm-m009 frame. They have been around for awhile and people seem to have had good experience with them. I was pretty impressed with the quality of the frame for the price.

I wanted a non boost frame in order to use wheels I have from my gravel bikes. Hard to find those these days.

Yes, the quarq and fork were used. I had the wheels and some of the other small parts. Most everything else were eBay finds.
