Where to buy 12-tooth cassette freewheel for single speed DJ

I'm having trouble finding a 12-tooth freewheel for my Deity Cryptkeeper. It appears 13 tooth is the smallest common size, but I've been told 12-tooth freewheels exist for cassette hubs -- is that erroneous info?

My rear hub is a Sun Ringle Disc Jockey.

Thanks in advance.

A "freewheel" threads onto a hub for freewheels.

A cassette hub uses cogs and spacers. It sounds like you are actually looking for a 12t cog, not a 12t freewheel?


can you use a bmx freewheel on a mtb hub?

Thanks, guys!

Cmc4130, I think you're right -- I think I'm looking for a 12-tooth cog. Here are some photos of my cog/spacers/hub which should confirm. Does this mean I can use the link adrennan posted and simply purchase a 12 T cog from the Profile site?

Profile cog only works on profile hub.
But you can find tons of 12t cassette cogs on eBay
My personal fav is the Gusset FatFoot but there are several good ones
Crupi is another good one.
