My neighbour just gave me a Fuji Ace frome the late '80s (at least I assume that's when it was made). It has Suntour Blaze Accushift shifters and derailleurs, and almost everything else is from Sakae or Dia Compe. It seems like a pretty nice bike, but I was wondering where it fit in the Fuji lineup? And also, did this model have 4130 cromoly or hi-ten steel? There is no decal identifying the tubing.
