Thanks @Nob . I hadn't thought of doing a search of eBay - doh.
Any idea if these things came in different specs as for sizes or the amount of travel the arm moves in and out?
The rear derailleur on my vintage (1985/86) Peugeot P 10M Premiere has finally died.
I'm looking for help on finding a replacement. Can anyone help tell me what I need?
Beyond the Simplex branding, I can't find any other model details on the defunct part.
