Front sprocket for 2018 stromer st2 replacement of large ring

I have a 2018 Stromer st2, where the front large sprocket is worn down and needs to be replaced. I've changed the rear sprockets a bunch of times with parts from amazon, but never the front sprocket. Has anyone done this, or know which part to order?

Thanks in advance,
Neal

Any 130mm BCD chain ring should work.
However, changing the chain ring size may impact the use of the stock chain guard.

Hi Insider, thank you for answering! I mis-typed my year...it is actually a 2013 st2. And it has a 110 BCD, which I just changed. No issue with the chain guard. Sorry for the confusion.
