NOS SIMPLEX SUPER LJ SLJ Vintage Down Tube Gear Shifters

The SIMPLEX SUPER LJ SLJ designation belongs to a specific lineage of French down tube shifters. This pair is new old stock, meaning the levers have never been installed, though the decades may have left minor cosmetic marks from long storage. The photos are part of the description; what you see is what you receive.

What makes this SIMPLEX pair notable

The SUPER LJ SLJ was a lightweight, friction-based shifter design. Down tube placement keeps the cable run short and direct to the front and rear derailleurs. For a vintage road build, that means a clean cockpit and a very period-correct look at the frame boss.

• Condition: New old stock (NOS) — unused, with possible light storage wear
• Type: Down tube friction shifters
• Compatibility: Designed for classic road drivetrains of the SIMPLEX era
• Relevance: Suited to restoration projects and Eroica-style bicycles

These levers pair naturally with a SIMPLEX rear derailleur from the same period. The SIMPLEX vintage gear shifters EROICA listing shows a related control option, while the Derailleurs category gathers matching rear and front mechs for a coherent build.

Condition note

Unused stock of this age can exhibit faint shelf marks, light oxidation on bare metal, or slight patina in the chrome. No major defect is declared on this pair. Examine each image carefully — the visual record carries the final word on finish and completeness.

The lever bodies and mounting hardware should be inspected against the photos before installation. For those assembling a complete early-1970s drivetrain, a compatible derailleur like the Simplex rear derailleur vintage bicycle Eroica Peugeot Gitane Mercier provides a matching endpoint for the cable run.
