Just catching up on all this, I've been away. Thanks for the tips, some good stuff here. The quote for repair is significantly less than what a new frameset would be, even with significant discount I think. I'll update on here when the repair's done. It will likely take a few weeks though :(
Just read you have the ONE cranks, I’d ditch those before a ceramic BB, for some hollowgram SI’s. Those ONEs are flexy boat anchors
