I am completing a restomod project on a late 70s Peugeot PX10. I have kept the original stronglight crankset (52/40). However, I coldset the rear stays and am using a SRAM 8 speed cassette (32/11). I am also using Shimano Dura Ace bar end shifters.
The rear drop out was tapped for modern derailleurs by a previous owner so I have options.
Based on my evaluation my drivetrain capacity is (52-40)+(32-11)=33. So I suppose I need a medium cage 8 speed derailleur.
Id greatly appreciate some advice on a good choice here. A friend told me that I might need a Dura Ace derailleur because the bar ends have a particular pull length. Can anyone confirm or refute that? Otherwise I’d love a rear derailleur that comes close to matching a vintage aesthetic.
Much thanks for the feedback.
