Where can I find a huge cog?

I can’t find any cogs bigger than 23t, but I really would like a 25t, or at least 24t. I’d prefer 3/32, but whatever.

Seen one around?

I’ll tell you if you can tell me where I can find a super small chainring.

Just do BMX cranks.

The shop near me, The Alt has giant cogs.

Any idea who made them?

Not one hundred percent.
I remeber a surly logo. but that was only like 20 teeth.
