This is a rather pleasant example of a late Simplex Vallée. Its features are:
- The outer parallelogram plate is black with capitalised logos in white.
- The knuckles are coated in an interesting bronze plastic substance - possibly Teflon, but possibly not.
- The cable route can be switched between 'standard spaced 5 & 6 speed sprockets' to 'compact spaced 6 & 7 speed sprockets' by rotating a small back plastic component.
- The pulley cage plates are black.
- The pulley wheel bolts have Allen heads
- The cable clamp uses an Allen bolt.
- The cable adjuster is silver.
This derailleur is notably similar to the Stratec RX700.
