You do know they made something very similar in carbon, right?
I happen to have one of these; built it as a sprint frame. Be aware that it is a road frame, made in a "gigantic" Taiwan factory. All Tange ordered was changing the road dropouts to horizontal, and locating them inward of the stays. The angles are 73. The BB height is only 10.5", so this frame does NOT work on steep tracks! But it is a very sweet ride nonetheless.
