Thanks. I actually bought this mtb recently to use it as a "model" to restore my PR6000 team bike (1991 Pro team) that had been resprayed (in a very bad way) by the previous owner.
1990 Shogun Prairie Breaker, Tange Prestige.
Shogun was an export brand of Marui Ltd, so it had just about everything on their books in 1990; Tioga (most of the catalogue!), Shimano, Strong, Araya.
