The frame is a fillet-brazed 650b steel hardtail. My goal was to create a frame with 650b-specific geometry that fit me well. I love the way it rides! It has a slack head angle, but the short chainstays and wheelbase keep it very flickable.
Some geometry specs:
69 degree head angle
72 degree seat angle
12″ bottom bracket height with 100mm Fox fork and no rider
I couldn’t be more happy with the frame I built at UBI. I hope to build many more.
