In the late 1980s and early 1990s Campagnolo produced a bewildering array of derailleurs that all looked extremely similar. This poses the perfect puzzle for derailleur geeks who can endlessly debate exactly which is what.
I think that this thoroughly abused derailleur, with its unusual Graphite finish, is an early example of a Campagnolo Record which may possibly have had the part number R010. I guess that it is a Record (R010) because it has ball bearings in its pulley wheels and a hex cable clamp bolt. I speculate that it is an early version because it has a spring adjuster on the p-pivot. There is probably someone out there who knows for sure - if that someone is you, please let me know!
A list of relevant details might include:
- There is a spring adjuster on the p-pivot.
- The cable adjuster is round and threads straight into the aluminium of the b-pivot.
- It has a double parallelogram spring using ~1.5mm wire.
- The inner parallelogram plate is a stippled aluminium pressing.
- The cable clamp nut is a hex nut.
- The pulley wheels are Campagnolo's typical ball-bearing design, in black.
- The inner pulley cage plate is aluminium and has no spoke deflector.
