Hello,

For a folder with 20" wheels, I'm thinking of getting a Microshift Super Short Acolyte Rear Derailleur RD-M5180S.

From Shimano, I already have a brand new eight-speed cassette (CS-HG41-8) and shifter (SL-M315-8R).

Microshift says the derailleur is "compatible with Acolyte shifters only": Is this true?

Thank you.
