10s & 11s Rear Derailleur? Shimano RD M4120 SGS First Look Initial Review

[@AbhishekKumar1902]

Hey thanks mate, just curious if this derailleur will work fine for 9speed and 8 speed cassette as well?

[@pedalpowercycling]

I don't think so, they (Shimano 8s, 9s) have different ratios.

That’s interesting🤔.
