Modern geometry with 25 years of experience. The OS-TIG features oversized tubes TIG welded to today’s modern geometry. The 35mm top and seat tubes and 38mm down tube create the stiffest and most solid steel bike you can make today. A custom 38mm head tube mates frame to the front end with almost no flex, as this is where you really feel its strength. A 6 degree sloping top tube and a BB30 bottom bracket creates a strong and stiff compact frame with a modern look, and a solid comfortable ride. TIG offers the advantage of being stronger after welding, and lighter as a result of less materials used. It is available with NOVA or Columbus steel, or KVA stainless steel. It can be paired with an ENVE or hand made Fuso steel fork.
