We recently picked this one up in Raleigh and put it back closer to original spec. It doesn't appear that they have serial numbers so 1990 is a guess based on Answer taking over fork production in 1991. This one came with both the rigid fork (pictured) plus a suspension fork. 115mm front hub, 145 mm rear hub, offset rear triangle, 90mm bottom bracket, composite fork, suspension fork........pretty advanced for the time.
