My 84 Club Fuji is quad butted 1769(whatever that means) It came with Suntour ARX, which I upgraded to Cyclone M-II. Original wheels were pretty trashed so I put on a set of 600 hubs with Mavic rims. The ride is quite nice! It also feels quite a bit stiffer than some of my other steel bikes when out of the saddle. I think you might be confusing quad butted with something else? I don't think they'd put it on a bike that went for $360 in 1984, if it was crap which rode awfully, lol.,,,,BD
