WC - Sweet bike... I love lugs.
I know that the Shasta was a straight gauge frame in 1987 (a friend has one) but my '88 Shasta has an EX butted frame, has a hand built decal, and is far lighter than it's predecessors. I wonder if the later model Sierra also got an upgraded tubeset ?
I always like to be able to ad to my Kuwahara / Apollo lore.
