Does anyone know if this is some chinese OEM frame?
well they dont build the frames themselve but i did not find the OEM
Judging by the paintjob of THEIR OWN product images, i guess they suck.
Just look at the MTB frame and the paint around the linkage bolts.
The frame itself looks like an iteration of the Edge Red Deer, aka Fina Trail Scout.
