Campagnolo Olympus O.R. MTB Rear Derailleur: Graphite Grey- 1990's #Z010-LG - Long Cage - Avitar Jockey
This late 1980's to early 1990's long cage Off Road rear derailleur is identifiable as Olympus via it's graphite faceplate and silver body. It was 2nd in the O.R. lineup in this era behind Euclid (which was all silver) and above Centaur (which was either all silver or all graphite).
These have been upgraded with period correct Avitar CNC anodized jockey wheels in silver. These are as smooth as Bullseye pulleys, but have even less side to side play.
Great to excellent used shape. It looks better in person than in the photos. The left pivot housing has some light scraping as does right around the limit screws. Minor marks elsewhere. Pivots and pulleys are tight and smooth.
- Designed for indexed (I.D. by the adjuster barrel)
- Issued roughly 1989-1993
- Long cage
