This is how I have it built currently. I apologize for it uncouth appearance. I was far to excited to ride it before finishing it.
It appears they can make/mold the frame for QR or TA no ability to go back and forth.
The bikes that I have own to compare this to are a 2016 Super X (44) and a CAAD10 (50). Disclaimer: I think sometimes handling characteristics are size dependent. This bike is in a far different category than CAAD, Super X and Super six's have ridden. Those bike are happiest when raced, pushed and railed in to corners. They all are generally snappy, lively and closer to nervous. They beg to be pushed a little harder or faster and would rather go around the rough then through. Although the Super X had good large bump absorption in the rear.
This bike is quite the opposite. It is asking you to ride a little longer to find rougher road you may normally avoid. Find a dirt road, side road, rough road, two track or even the occasional single track (single track is a theory I still need to confirm). The bike felt planted and wanted to ride straight through the rough. The vibration dampening/ride feel was closer to muted compared to the lively feel of the others. I have had similar conclusions comparing some high end name brand carbon mountain bikes to there open mold alternatives. Although it is difficult to pin ride quality with tire size being so different. It felt good going up hill. If felt planted as always and stiff going up hill with very little sense springiness or snap like a Super or CAAD.
