Question for those of you with the Specialized Aerofly II bars

I am likely going to try and grab these in the next few months. I noticed that the bars don’t come with the stem or face plate for the stem.

So…I am guessing I will need to buy the stem along with the bars?

Should I get the “Tarmac” stem or the future gen stem?

Thanks

*Also, anyone know of any shops that might have these on discount 42 width?

You can just use a standard stem.
