I screwed up. I asked a buddy if all shimano 11 speed cable pulls were the same for road and mtb. He said yes. I bought a M-5100 derailleur and just discovered that he was very wrong. The 105 11 speed shifters on my gravel bike don't work. Found out that 11 speed uses 1.4-1 ratio apparently. I bought a 11-46 cassette too which I really want to start using. Looks like my options are a 45 dollar cable pull adapter or a 80 s-road rear derailleur, or maybe a goat link and using my old 105 with the wide range cassette?

Any other suggestions?

If you know exact pull ratios and you want to try some hacking,
you can change pull ratio by moving cable entry point to change leverage
for example, by drilling offset holes in arm

If this is any help it shows most derailleurs available and their pull ratios. Bicycle Cassettes & Drivetrains - Google Sheets

The Wolftooth Tanpan will make that setup work: https://www.wolftoothcomponents.com/products/tanpan

I use one with 105 shifters and an 11-speed XT rear mech. Works great.
