Hi all! I've been lurking around on this forum for some time and see quite some interesting builds passing by. I'm planning to build a gravel racer for myself and the Airwolf yfr068 caught my attention. Still contemplating if I should go for that frame due the headset bearing issues...

After some research I came across the Superior X-ROAD, very good looking frame if you ask me. Anyone an idea which frame this is based on?
