I think you're asking the RD to wrap too much chain. there is no spring ( or did the later ones have one?) in the attachment point so all you have is the body / cage pivot.
back in those days guys running 39s front usually had 21 or 23 for the 'easy' gear in the back
anyone know max tooth and wrap for a late gen C-Rec?
according to VeloBase the max cog for a 2gen is 28t and max wrap is 27t. I think you either need a smaller cog in the back or live with the chain being a tad slack
