[Front crankset] Replacing outer ring with chain guard?


I'm currently using a 50/40/30 triple crankset + derailleur on a Brompton where I 1) removed the outer 50T, and 2) replaced the middle ring with a 46T.

I'd like to install a chain guard as the outer ring.

Would this product work if I chose the "use on double chainring" option? Should I order a 46T, 48T, or 50T?

Out of curiosity, how do the single/double chainring models differ? Why two models?

Thank you.
