Subject line says it, a 24mm JPR aluminum one-piece post with unique rocker cradle, 2-bolt, true micro adjustment and normal offset.
Intricate French castings, road length, fits several years of UO-8 (known 1978-1983, likely others).
A critical upgrade for proper saddle adjustment, reduced weight! Ebay found no buyer.
