Titanium Bicycle Frames

Bingham Built makes custom titanium bicycles, sold as frames or complete bikes, for gravel, all-road, road, mountain, fat bike, adventure and tandem riding. Every bike is built to order with no stock sizes or set models, and finishes include bead blast, brushed and etched logos. Builder Brad Bingham worked about 15 years at Moots, then took over Kent Eriksen Cycles when Kent Eriksen retired in 2017; Bingham Built carries on that shop.
