Since my current bike is QR, I'd need new wheel. Since I'm both on road and in forest, I need 2 sets Plan is 1 set with communting/bikepack tires. Somethink like 32mm Continental 4seasons, and 1 set with graveltires (running 33mm challenge limos now, but guess that is more of a cross tire).

Probably too late, but the GF01 is an open mould that is available from several brands and some sell them with quick release dropouts for frame and fork. For example haidelibikes (tideace) or spcylce do.

Maybe velobuild can provide the frame with qr dropouts aswell. For the frame, you can even find them sold individually on aliexpress. Of course, for the frame it is either or...

I have that frame though i bought from tideace. I didn't know of velobuild back then or else i would've bought from them. The frame itself is a copy of the Open UP,  and like the Open it is very road bike like. It's great but has one major flaw: no 0-setback seatpost. The Open was designed for 0-setback back, so with the same seat angle but 25mm many people won't find the perfect seat position. If you got long femurs you'll be fine. If your femurs are normal or small for your size... You might have a problem.
