Hello, I recently purchased a front end rear fore brakes! Question is the rear sprocket, it's 16 tooth and like always riding uphill! Wondering if there is other options for sprockets, does other brands work or schwinn only? Anyone have a 20-22 tooth sprocket that will work on this hub? Wanted to ask here first before I post in wanted section... thanks for your knowledge...

Will be curious what you find out. I have 2 bikes with the rear hub like yours and have the same problem.

From Schwinn lit that I've seen, they only offered a 16-17 and 18 tooth freewheel sprocket.

16, 17, 18 freewheels were offered on the early 38-39 dural rear hub. I think other period euro freewheels fit and come in other sizes.

14, 16, 18, and 20 (8 & 10 1" pitch too) rear cogs were offered on the later 40+ drum (like you have pictured above) that used a proprietary freehub assembly. It shares that assembly with the same period large flange rear hubs, so one of those might be a source for the 20 you seek.

Here is a set of '40 BA Special wheels, you can see the 20t on the rear.

I had one of these before and I removed the cog from hub and took them it into a bike shop. Bike shop owner looked at it and handed a 20 tooth cog, thread right on and worked like a charm. Cant remember the brand but I remember it was for a BMX.

You could get the smaller 46 prewar clover style sprocket instead of the big 52 tooth
