In the background, we carry out simple and polite frame building while making full use of the basics of bicycle manufacturing cultivated in Santa Cruz Bicycle, which continues to discharge many world champions, and the knowledge and wisdom of the latest materials. This Black Cat Bicycle is manufactured by Todd Ingemenson, a rare builder who also does his own unique paint work, at his workshop in Aptos, California, USA. Bicycle manufacturing technology using delicate welding and machining, which cannot be grasped only by the frame of a modern and stylish custom motorcycle, firmly leads the history cultivated by many California builder ancestors to a new generation. One of the builders to go.
