Looking for sprocket for this rim

Hi. Looking to get a sprocket for this rim. Thanks!

Like an original factory sprocket? Or just something with five holes? You might want to know how many teeth, too.

Factory would be cool, but I would settle for anything that works lol

I actually have the newer style sprocket and hubs for a few of my bikes. I just picked up these rims, I’m gonna use these for one of my choppers, that’s why I’m looking for an original or at least a good replacement

me personally I whould stay away from that rim
to hard to find that sprocket . If u find it more than likely
it will be bad and crap

I’d probably buy one of these “blank” sprockets and drill my own holes. https://www.ebay.com/itm/2234363705...lOrd06oQbO&var=&widget_ver=artemis&media=COPY

Have you looked to see if this is the same pattern as the commonly used split sprockets? If anything you can then use the split sprocket as a pattern to transfer to a non drilled sprocket.

What is the mounting bolt circle measurement ? What chain size- #35 ?

 

[novadose74]

I didn’t even think of the split sprockets. I can take a look.
i can measure once I get a chance

My Original tablocs and sprockets are packed away, they are the first version (1" wider than your 2nd gen version) but the bolt pattern on them matched what Rupp used for a spell with disc brakes. I doubt they would have changed the pattern when they changed the wheels but they could have. I had installed 1968 Rupp disc brake parts on them years back for a custom build I was working on. I don't know if that is the same as the 5.125" pattern that Azusa still sells or not though? Have you properly measured them?

Here is the measurement, 6 3/8

If you end up not finding a sprocket for the rim you can buy a blank from BMI and have it sent to me and I'll machine the bolt pattern for you. No charge. Shoot me a PM if you go that way.
