Campagnolo Chorus Aero vintage seatpost 26.4mm 1990 Colnago Gios

26.4 mm of cold-forged alloy that anchors a saddle to Italy’s most revered steel frames. The Chorus Aero seatpost emerged when Campagnolo’s second-tier gruppo gained a sleek, sculpted profile, matching the aerodynamic trends of the early 1990s. This post, stamped “Chorus,” delivered a racier aesthetic at a lower price point than the Record, yet retained Campagnolo’s tight machining and secure two-bolt rail clamp.

Aero Profiling for the 1990s Italian Build

The elongated teardrop shaft and integrated clamp head reduce visual bulk behind the top tube. On slender steel frames by Colnago, Gios, or Bianchi, the post’s fluid lines echo the tubing profiles. Despite its aero form, the post’s 26.4 mm seat tube fitment remained a staple on countless professional-level machines. The alloy shaft provides ample stiffness for confident pedaling without harshness.
