By rights the Simplex Prestige Super LJ (SLJ6600) should have been up there with the 1983 Campagnolo C-Record and even more so with the 1978 Dura-Ace EX (7200). It has the geometry of the Shimano Crane, sports a silky anodised finish and was the top-end model of a brand that won the Tour de France in 1977 and 1983.


But it somehow never quite made it into the top flight. There are lots of small short comings - close up the finish is quite nasty, the Prestige Super LJ (SLJ6600) uses Simplex’s proprietary hanger bolt which kind-of fits a Campagnolo drop out but also kind-of doesn’t fit and, to combat Shimano’s Dura-Ace AX (7300), it is cynically labelled ‘aérodynamic’ without actually paying any attention to how air flows over it. Most importantly I found these derailleurs to be less than reliable - in particular the springs seemed to loose tension faster than you can say ‘ça plane pour moi’.


All-in-all Simplex seemed to think that they could make a competitive top class derailleur without really pulling out all the stops and covering every detail - they were wrong - those days had long gone by 1982.


Must try harder.
