For the 1992 model year Campagnolo finally launched a Record derailleur with a concealed p-pivot bolt - catching up with the look that Shimano had introduced with the 1986 Shimano Santé. The new Record was a broadly satisfactory object, with a fine finish, a certain solidity and reasonable indexing performance.
However, at its introduction it weighed an elephantine 260g, compared to around 190g for the Shimano Dura-Ace 7400 series. Campagnolo put the Record on a diet for the rest of the 1990s introducing a series of incremental improvements, each marginally lighter than the last.
I am aware of 9 possible variants. A listing of them, with probable dates, might be:
- RD-01RE, from early 1992, had a polished, cast, inner pulley cage plate.
- RD-10RE, from later 1992, sported a stippled, pressed, inner pulley cage plate with a simple shape around the tension pulley.
- RD-11RE, from early 1993, featured a stippled, pressed, inner pulley cage plate with a pointed extension at the tension pulley.
- RD-11RE, from later 1993, had a stippled, pressed, inner pulley cage plate with a spoke protector flange. Logic would suggest that this should be RD-12RE, but, confusingly, seems to be called RD-11RE.
- RD-21RE, from 1994, saw the introduction of 8-speed pulley wheels with a self centring guide pulley.
- RD-31RE, from 1995, sported the word 'Record' on the outer parallelogram plate.
- RD-41RE later coded as RD-08RE, from 1996, featured the words 'Record Titanium' on the outer parallelogram plate.
- RD-09RE, from 1997, had the words 'Record Titanium 9 Speed' on the outer parallelogram plate and a steel cable clamp washer with a single 'prong'.
- RD-19RE, from 1998, also had the words 'Record Titanium 9 Speed' on the outer parallelogram plate but had an aluminium cable clamp washer with two 'prongs'.
I believe that this example is an RD31-RE, the fifth iteration of this basic design. The clue lies in the words 'Campagnolo Record' written on its outer parallelogram plate.
This is an 8 speed derailleur.
A list of relevant details might include:
- The logo on the outer pulley cage plate is the Campagnolo signatureaccompanied by the word 'RECORD'.
- The b-pivot bolt and hidden p-pivot bolt are chromed steel.
- The cable clamp bolt is Campagnolo's signature combined Allen key and hex design.
- The cable clamp washer is steel and has a single 'prong'.
- The pulley wheels are Campagnolo's 8-speed pulley wheel set with a self-centering guide pulley.
- The inner pulley cage plate is a stippled aluminium pressing with a spoke protector.
I remember being deeply disappointed with this derailleur - when manufacturers release 'new' models where the only 'improvement' is to the writing on the outer parallelogram plate, you know they're in trouble. But Miguel Indurain just kept on pumping in those Tour de France victories regardless.
