Looks rad! Is your BB just hanging out there in space? Might want to add a strut between the BB and seat tube for support. When I’ve attached the ST to the DT like that (2 or 3 frames of that design) I’ve always added some support for the BB because I’ve read about breaking otherwise. Though I’ve never *not* tried putting in the extra strut, so I could easily be full of it. Agin, nice work!
