Campagnolo C-Record and Nitto S65 single bolt posts aren't indexed.
Campagnolo Record SP10-RE round post. Infinitely adjustable, holds its adjustment with low torque, correct diameter, shiny silver, worth the $100 used ones sell for. Also available with a discrete Record logo consistent with 9 speed ergo era aesthetics.
Classic Campagnolo C-record aero post. Works like the later round version. Period correct for 1980s bikes. Available as a Record part with engraved shields plus collectable price tag and Chorus without.
Nitto S65. Mine needed 16 NM of torque to maintain its adjustment so I replaced it with a Campagnolo SP-10RE.
