I have a feeling if they are really cheap they are coaster brake cogs and those wouldn't work. Post a link to one of the ebay cogs.

I discovered I have a 16t in the stash so I am going to try that with my 42 ring, so about 67 inches. Normally I'd say that's low but for this bike I might actually want something lower still. Time will tell.
