Not my work bench is the issue here ben, honest!
Neil, the build is a hopefully time proof steel (obviously) XL 29er. 44mm diameter 120mm long head tube, 3 sets of bottle bosses, 142×12 rear drop out, rear triangle geometry as such; 450 chain stay w/ 73.5deg seat angle, 55mm BB drop. 70 deg head angle with a 490ATC measurement (for rigid forks with a external Hope H cup), will also run a 100mm fork up there at some point. Will also have a 630mm ETT with ~540mm seat tube. I could link you to previous posts or to blog spam but I’ll save you the boredom 😆
edit: and a standard threaded BB shell, none of this press fit rubbish.
