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!
Its a crappy water bottle mount; I'm only using it because its titanium (like the rest of the bike). My other one has a better holder on it.
You should sell these, the "Green Enduro & Ham" or "Berms over My Hammy"?
