San Marco G.S. Gran Sport non-fluted Seatpost: 25.4mm - Highly Polished Alloy (EXC+)

Current Stock:

Product Description

This San Marco GS post has a higher polish than most of this model.  Perhaps it was polished aftermarket.  it does still hold just fine in a 25.4mm frame, it came to me on our 1960's Urago bicycle and was rock solid. This size is used by many of the "screwed and glued" bonded alloy/carbon frames such as the Vitus 979 / 922 and various Alan models, as well as 1940s to 1960s French road/rando frames.


Excellent to near mint shape with a lovely polish.  Above the inserted area it is show worthy with the exception of a long insertion mark up the front side of the post and the clamp pieces have the very beginnings of pitting spots.


  • 25.4mm x 200mm long
