I sent them an email as well. They told me the frame will not be out for sale before the end of 2018...
Apparently they have another 29er frame with boost which is on stock. It is called FM199-B. It seems to have the geometry of the workswell 062 with a 31.6 seat tube, interated rear axle as well as the boost Standard. So if you like that geometry maybe it would be worth looking at. Speaking about it. Has anyone experience on the FM199?
