STRONGLIGHT Seatpost 26.6mm Vintage Eroica Bike TS43

STRONGLIGHT 26.6 mm Seatpost for Eroica and Classic Builds

Finding the right diameter is the first battle when building a period-correct bike. It is made of aluminium and was manufactured in France. The post shows no oxidation.

26.6 mm is a diameter that appears across a specific generation of French frames. STRONGLIGHT supplied components to many of the workshops that built racing and touring frames in that period, so the branding sits naturally on a French restoration.

Why the Diameter Matters Before Anything Else

Seatpost sizing is unforgiving. A difference of four-tenths of a millimetre decides whether the post clamps or wobbles. Measure the seat tube with a caliper, or check the frame's original specification, before buying. If your frame calls for 26.6 mm, this post fits without a shim.

For a broader view of the parts that complete a French restoration, the Saddles & Seatposts category gathers compatible options. Riders chasing the Eroica look often pair a post of this diameter with a Vintage RUBIS SV 610 Seatpost 26.6 mm, while those who need a slightly different fit can compare it against the SR LAPRADE seatpost 26.6 mm for Peugeot Eroica.
