Freewheel threading on Miche flip-flop hub

Bicycles Asked on January 1, 2021

I’m currently building a parts list for a new single-speed bike. In the process, I came across a nice looking flip-flop hub from Miche: The “Primato Pista/Strada”

I figured that adding the fixed sprocket is best done using a dedicated Miche carrier. However, for the freewheel sprocket, I’m confused. I read about Italian, ISO and British threadings, all being approx. 35×24 tpi. On the referenced website though, it states that the freewheel is 36×24 tpi, which seems too large for regular freewheel sprockets. I couldn’t find any suitable sprockets online.

Is it possible to just use regular Italian freewheel sprockets on that hub (as for the fixed sprocket)? If not, where can I find suitable freewheel sprockets?

I have these hubs, I used a normal freewheel (1.37" x 24TPI) I had lying around from my old single speed build.

I'm 99% sure you also need a normal single speed / BMX / trials freehub. The 1% doubt I have is, that I don't know which model/year your hub is. And I don't know if they ever did a different one.

Worst come to worst, buy a freehub from a place which does refunds easily. That way, you can try to fit the freehub and if it doesn't fit, just get your money back.

I built a pair of wheels with Miche Primato Strada/Pista with a Sturmey Archer freewheel SFS30.W190.CA0 (19 teeths, chain: 1/2" 1/8"). No problem for setting up the freewheel on the hub.
