Croder chainring question

[GolfCycle]

I am considering a Croder 46/30 chain ring. Croder sells a derailleur extender. Do I need the extender for the front derailleur stalk on cruzbikes. I have a V20c if it matters.

Thanks
Stewart

I installed 46/30 Croder cranks on my V20c and did not need the FD extender.
