Shogun manufactured a modified double diamond frame with a top tube that was horizontal at the rear and sloped upwards at the front (see diagram). The design allowed them to produce a frame with a very short seat tube without having to resort to a mixte style frame or a small diameter front wheel. The design was cost effective in that all it required was an appropriate bend in the top tube. The seat lug was a standard design and the top head lug or bulge formed head tube was that from a ladies' frame.

Typically, the smallest lugged, double diamond frame with a horizontal top tube is around 19-1/2". Below that , the the top tube intersects with the down tube, providing insufficient head tube length. The solution is a mixte or ladies frame or a smaller front wheel, the latter which extends the head tube downwards. Shogun intsead chose to retain a standard head tube length and front wheel size, putting a bend in the top tube. All these apporachs became moot with the adoption of TIG welding, which eliminated lugs and provided infinite angle choice. Straight top tubes which sloped downwards to the rear became standard for small TIG welded frames.

The Shogun 100 was an entry level model. New, circa 1985, they were only a $169.00 US bicycle. Used ones, in average condition, in an average market, would probably be worth $50-$75 US. Given the frame design, it almost certainly a very small frame. Typically, this makes them harder to sell and get a good price.
