Why do you want 9t ? Remember, gear ratios are not going to be the same as with bmx 20"s when you have 26"s.
25/9 X 20" = 55.5 gear inches
25/11 X 26" = 59 gear inches
28/13 X 26"s = 56 gear inches
etc.

41/18
39/17
37/16

All are your most common 24" combinations, but if you like a little stiffer gear you can go up a tooth in front on those combinations. Another good rollout for small gears is 30/13 at 55.4. Technically 23/10 at 55.7 is good too, but there are so few options in a 23t that it doesn't make it practical.

Here's an article I wrote on gearing that covers most. Where 41/18 is still a common size, I did not include it in this article as it does not actually hit the 55 rollout mark. I believe it's actually 54.9. Really close and probably should have included it since it is very commonly used. I just elected not to when there are other, and in my opinion, better options out there.

25/10 X 24 = 60. Pretty rad in my opinion. Slightly stouter than normal but still reasonable.

LOL I suppose that would depend on what you're doing with it. With racing, "slightly" would be an understatement. That's on the verge of insain. I could see someone running at 56.something, but to push 60 for a hard lap, dude's on the juice. LOL

Non-racing stuff is always rider preference because it's only you and the bike and whatever you're comfortable with.

Edit: 26/11 would give you a 56.8 and that probably wouldn't be too bad.

Yeah I hear ya on bmx tracks because its all about getting out in front on the gate start, but it's pretty common in the DJ/street mtb scene as well as BMX street to have gear inches in the high 50s low 60s. A lot of 20" Bmx guys here in Austin ride 28/9, which is 62 gear inches. I have one build with 72 ! The SS/Fixed road bike scene uses mid 60's to mid 70s gear inches.

That is insain. Smile I had a mental picture of the reverse for vert. Don't need gears because the drop in does all the work for you. Just slap a front wheel on the rear with no front sprocket, just some spindle and crank arms and have at it. LOL
