Simplex

Classic Simplex Rear Derailleur

New, old stock, similar to the classic "Prestige" model used on many bikes in the 1970's.

Good for restorations, but shifting performance is not nearly as good as modern derailers.

Not designed for indexed shifting

This version has a built-in adaptor claw, fits frames with plain drop outs.

NOTE: The cage plates have some oxidation from sitting around over the years.
