Close up of head tube-main tube junction. Inner tube scraps make for a "sealed" headset. A cut off steel handlebar stem was brazed onto the back of the fork steerer tube, so the handlebars attach directly to the fork. A small tube was inserted into a hole through the main tube and brazed, and serves as the mount for the front seat frame tabs. Steering is very neutral. I went for a 72-ish head angle vs. the 73 degree angle that was on the BMX bike the fork came from.
