I have plenty of more period-correct long cage RDs that can be used on this bike in place of the modern Alivio. I may try to complete the group with a long-cage Arabesque. So is what's on this bike considered (600) Golden Arrow or (105) Arabesque? The brakes are BR-Z57, so I assume that corresponds to 105. And what's the difference between Golden Arrow and regular 105?
