This is a pleasantly clean example of a Simplex Fun Bike. Its features are:
- The outer parallelogram plate is black with a logo that a middle-aged French bicycle component designer might think is 'funky'. there is also a ridge along the bottom to protect the adjustment screws.
- The derailleur is claimed to be coated in Teflon. The knuckles do appear to have a plasticised finish.
- 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 and possibly Teflon coated.
- The pulley wheel bolts have Allen heads
- The cable clamp uses an Allen bolt.
- The cable adjuster is black.
This derailleur is notably similar to the Stratec TS700.
