Simplex vintage rear derailleur Peugeot 1960

The Simplex name on a rear derailleur from 1960 points to a specific chapter in French bicycle component history. This one is listed as a Peugeot-era piece — the kind of part that surfaces when a period-correct drivetrain needs putting right.

What This Part Addresses

Rebuilding a 1960 Peugeot usually comes down to finding the right derailleur. Not just any derailleur. This Simplex unit answers that need without introducing anachronistic components. The listing is for a single rear derailleur, sold as shown.

Condition and Inspection

The existing description is deliberately short: the photos are part of the description. The visual record carries the real condition detail — wear, finish, hardware, and any signs of age are documented there. Read the images as the primary specification.

For a complete drivetrain setup, compare it with the Derailleurs category or a related Simplex rear derailleur for Peugeot, Gitane, or Mercier builds.

Compatibility Notes

No technical specification sheet is provided for this item. The correct approach is to verify mounting type, cage geometry, and chain wrap capacity against the frame and freewheel you intend to use. A Peugeot 1960 drivetrain will typically demand period-correct cable routing and chain width. Confirm those details before installation.
