|when did shimano dura ace rear hub come out as a freehub(cassette?) and not a freewheel?
and what's the largest cog the old shimano 600 'arabesque' rear der. can handle?

|I can't speak to Dura Ace, but I still have a Shimano 600 freehub from a bike manufactured in 1979.
Product literature on for the 600 says 28T largest cog.

|Dura ace came out in 7-speed in 1986 (7400 series). At that time you could have either a cassette/freehub system or a freewheel/threaded hub system. Supposedly, that option was only available for DA; 600 & 105 users had to go cassette to use 7-speed.
I have a component group from a 1987 Trek 2500 that is 7-speed indexing with a freewheel. I know that Shimano never made any 8-speed freewheels. So I guess they stopped making freewheel hubs when DA went 8-speed (7401 series) in 88 or 89.
I had seen an article about this somewhere, but sure can't find it now. Hope that helps. -Dave
