I talked with both USA and Asian reps for about the KHS folders today at Interbike. They said the folder market in the USA is just not active enough to justify importing the same great folders they offer in Japan.
I saw the KHS F20-R as pictured below and it is a beauty, 18 speeds with 2 front chain rings, 11.5 kg. They told it will retail in the USA for about 1 grand. At this time they are planning on importing only 10 units. I hope to get in one for us. I don't think it will last long.
