Vintage Steel Seatpost 23.6mm Peugeot Eroica TS40

A seatpost that doesn’t fit ruins the feel of any classic build. For many Peugeot frames from the golden era, the correct post measures 23.6 mm. This steel post slides in perfectly, clamping securely without shims.

Precision Fit, No Compromises

The 23.6 mm diameter is the specific internal seat-tube dimension required by numerous Peugeot road frames from the 1970s and 80s. It’s not a modern standard size, so finding a direct replacement off the shelf can be a headache. This vintage part eliminates that problem, offering a bolt-on solution that keeps the saddle exactly where you want it.

Eroica-Approved Authenticity

Whether you’re prepping for L’Eroica or simply honouring the legacy of French cycling, this genuine vintage component delivers period-correct aesthetics. The steel construction provides the right balance of flex and durability—something aluminium alternatives often miss—and the natural patina tells its story without structural compromise.
