SIMPLEX vintage front/rear double shifter clamp Mercier Gitane Eroica steel 1960

This is the SIMPLEX front/rear double shifter clamp, a steel component identified for Mercier, Gitane and Eroica bicycles from the 1960 period. It answers the question of how to mount a pair of shifters on a frame without adding separate brackets: one clamp, two positions, correct cable routing.

What this double clamp does

The part keeps the shifter area tidy. Instead of two individual bands, a single SIMPLEX clamp handles the front and rear positions. Steel is the material named in the item record. The naming references Mercier and Gitane, both French marques, as well as Eroica use.

Because the existing record is very short, the photographs carry the condition information. They are the reference for paint wear, metal state, and any marks from use.

If you are grouping cable routing and shifter mounting for a period build, this clamp belongs alongside a cable guide such as the Vitus Dépose vintage double cable guide. The two parts meet different needs in the same zone of the frame.

Positioning and period use

The double designation means the clamp is not limited to one side. On a Mercier or Gitane frame from the same decade, that allows the shifters to sit in the expected front and rear positions. The absence of a model code beyond SIMPLEX keeps the part readable across several 1960s machines.

A period shifter pair is a natural companion. The SIMPLEX vintage gear shifters 1970 PX/PY 10 represent the same French shifting line, a generation later in detail.
