my knowledge 3/10.
Shimano Alivio rd-3100 rear derailleur : I remove then fit .

bike : 2 x 9 speed ... front derailleur 34-50 : rear cassette 11 - 42

Make a bit of a mess of it but you get the idea.

Alivio rd3100 is Shimano's latest Alivio range (began 2020).
I guess it will be superceded by the new Shimano Cues.

Shimano is 'retiring' most lower 'brands' for CUES (?)
mtb : Altus, Acera, Alivio
road : Claris, Sora, Tiagra

Alivio is for 9 speeds (up to front triple ring ... so max is 9 x 3)
official rear max cog is 36 (mines works with 42)

cost : £14 ? (Ali Express sep23)

this is part 3 of Alivio filming week (not including 'short').
