Can I increase the size of chain ring on my 2021 Whyte V3 Portobello ?

Currently my V3 Portobello bike is fitted with an 11-42T cassette and an un-identified factory spec 1x 42T, 4-bolt 110 BCD chain ring. I would like to increase this to 44T. Shimano info for the derailleur (RD-M4120-SGS) suggests a maximum capacity of 41T with a maximum front difference of 10T. Since this is a 1x drive train the front difference is always 0T so it shouldn’t matter what size front chain ring I am running (aside from implications of chain length) – should it ?

    Correct, you can run whatever size chainring you want.
