I'm not sure which version of the Dura Ace that is but it should work with at least a 26 or 28T largest cog.
Thanks! I'd be pretty happy if it'd work with a 28T!
Atthis point, as for the der. angle, all I have to go by are pics.......as long as it's nothing obviously unfixable, like a busted internal spring or something, I'll be happy. (I heard that these Shimano der.s are not serviceable/can't get parts for 'em... and I don't want to have to replace one when I'm paying top dollar for an old bike)
