And after 8 years, what decision did you make? I'm undecided whether to try to preserve my touring bike with parts from its era or to go for a Neo Retro build, because in the end, the price is the same since vintage long cage derailleurs are very expensive and there is always little information about their capacity to handle a triple chainring. I considered the following long cage versions:- Simplex SX410 GT (The original that my bike had)- Simplex SX610 GT- Simplex SLJ 5500 GT- Simplex SLJ 6600 GT- Simplex SX440- Simplex Fun Bike- Huret New Success - Huret Jubilee- Huret Duopar- Sachs Huret Rider- Sachs Huret Eco- Sachs Huret New Success 84- Sachs Huret Rival 84- Sachs Huret Aris Rival ATB- Sachs M7000- Sachs Neos- Sachs Quartz- Suntour RD GT / FD Spirit- Suntour Cyclone- Suntour Mount Tech- Suntour V GT Luxe- Shimano Deore DE20- Shimano Deore M700- Shimano Z505 GS... And the conclusion is always the same: a Shimano GRX RX400 with Dia Compe ENE 11s friction shifters (despite being 10-speed, they have the 11-speed pull ratio) ends up being the same price or even cheaper in some cases.
