I've been going through threads looking for an answer....

My hub diameter is larger than my sprocket's center hole and nearly the bolt holes. I don't know if this hubs a keeper or not (its a sturmey archer s3c) so I'm trying not to buy anything hub specific (manic mechanic) or expensive

Can I buy (or refab my sprocket) a larger diameter center bore and bolt hub with the rag joint and half moons?
I could use some ideas on this...

thanks

Thanks broHSI


The flange diameter (the largest diameter on the hub) is 7cm so I'd want to rebore to probably 8cm.
The bolt hole diameter are 6mm but they would need to be "moved out" on the sprocket to make room for the hub diameter.

I spent some time looking around the forum for an answer the best I've seen is coaster brake conversions. I need a larger rag joint and half moons to refab my sprocket.

usabikemotors have a hub conversion kit the only thing is you have to take to a bicycle shop to get it re spoke with this it will give you a brake
