PHILIPPE Stem for Peugeot PX/PY10 100mm / 25.4mm / 22.2mm Vintage

Fitting a PHILIPPE stem means matching three diameters and one length. This unit records a 100 mm reach, a 25.4 mm handlebar clamp bore, and a 22.2 mm quill diameter. Those numbers decide whether it will drop straight onto a Peugeot PX or PY10 cockpit without forcing anything.

Why the PHILIPPE designation matters on a PX/PY10

The stem carries the PHILIPPE name, a marking that places it inside the same French component ecosystem as those two Peugeot models. On a frame where the headset stack and bar centre line have to align precisely, the 100 mm extension taken together with the 25.4 mm bar interface functions as a defined front-end package rather than a generic replacement.

The existing photographs show the piece from multiple angles. They function as an integral part of the description, documenting the overall condition and surface state of this used component.

For a matching front end, a PHILIPPE aluminium handlebar with a 25.2 mm clamp area appears in the related listings, while a shorter AVA stem for Peugeot PX10 builds offers a different 80 mm reach when the position needs to come back toward the saddle.
