C-Record Aero Seatpost

Brand: Campagnolo

The C-Record Aero seatpost (model A0R2, also found as A0RT) was Campagnolo's flagship seat pillar of the Corsa Record era, produced from 1986 into the mid-1990s. Its teardrop aero shaft and polished finish matched the design language of the fluted C-Record crankset and the Delta and Cobalto brakes, and versions were made with and without the engraved Campagnolo shield on the side. The single-bolt micro-adjust head is operated with a 6 mm Allen key and clamps standard round saddle rails of the period (rail fitment era-typical, not explicitly stated in period documentation). Forged in aluminium, the common 210 mm version weighs about 230 g, with a measured setback of roughly 25 mm. Per the 1988 Campagnolo catalogue it was offered in diameters from 26.0 to 27.4 mm in 0.2 mm increments to suit Italian steel frames; a near-identical Croce d'Aune version (C0R2) shared the same architecture.
