yeah it’s kinda interesting how poorly documented a lot of it is. I think partly because indexing a double is very easy - as long the shifter pulls enough cable, you just need to pull the derailleur into the right position on the big chainring and let it rest against the low limit screw for the small chainring. All I really know is: 1. back in the day, Shimano MTB triple derailleurs had _slightly_ longer arms than their road counterparts, which meant you could usually just _barely_ get a MTB-triple-on-dropbar-levers setup working, abet with the chain maddeningly rubbing in the lowest and highest gears. 2. Shimano road doubles moved to a much longer cable pull for road 11-speed: 5800, 6800, 9000, R7000, R8000, R9100, and RX810. And then this trickled down to 10-speed Tiagra 4700 and GRX 400, and something similar to 9-speed Sora R3000 and 8-speed Claris R2000. (so I’d expect that 4700 is going to work about the same as that 5800 shifter) 1. At some point, Shimano MTB stuff moved to a _much_ longer front cable pull. I’m much fuzzier on exactly when this rolled in… I _think_ it was with 11-speed XTR/XT/SLX? I never really touched 10-speed MTB stuff but the derailleurs looked basically the same as before, whereas an 11-speed XT triple shifter that I bought for some reason pulled a frankly shocking amount of cable per shift when I tested it. No idea if or when that longer MTB front cable pull has trickled down through Deore/Alivio/Acera/Altus. --- _[View the full topic](https://tarck.cc/t/did-you-just-shartq/23)._
