Wanted: Unlikely, but... pair of Goldtec hubs

I have one question though: how was able to fit a standard (i think) dura ace cog on my miche hub? whats not compatible? only the lock ring? I got a new one, but miche too. it seems better quality than the one that came with the hub..

On the new Miche stuff just the lockring thread is different, Campag ones or Phil ones or something fit but it's a pain.
I had an older Miche Primato and it had crazy size track nuts too, couldn't get replacements, just had to watch them go rusty.
Gladly rid of it now.
