The Cloud 9 was a one year bike for 1993 and used the same frame as the Lightning model with lighter parts.  The original bike used an odd mix of Suntour and Shimano components with a Breezer crank and a whole host of Ti bolts.  The claimed weight was 20.9 pounds for a complete bike.  Production was about 50 units for the year.  This particular bike was likely stripped of its parts and sold as a frame only and then built with a pretty conventional Suntour XC Pro parts package.
