525 Sprockets available?

[jfinnan]

I ask, because I have a brand new EK 525 X-Ring chain that I would like to use. I bought it for a different bike, and ended up not needing it. So, I thought about the possibility of switching the front/rear sprockets to 525. MikesXS only has the 520 and 530 sets.
