Simplex Vallée (3rd style)

Simplex Vallee (3rd style) main image


This is a rather pleasant late version 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.
