That's not a bmx cassette hub so none of the info in this thread will help u. Your going to need to find a ss conversion kit but i'm not sure how small sprockets for conversion kits go. I'm going to guesss 9t maybe.

About 12T would be good. You could get a 9T from a cassette, but it wouldn't be as strong as a SS cog. It also wouldn't be as good for your hub as far as wear goes. Chains wouldn't stay on it as good, etc.

For 26's, 25:12 or around that is good. 24's, 28:12 or around that is good. I see no need of going lower, but if that's what you're into go for it. It wears faster and isn't as smooth riding once you start riding 23T sprockets and the such.

for how to do your own ratio's...

sprocket size divided by driver(rear cog) size times wheel size

25/12x26= 54

you want the end number to be as close to 55 as possible...
