What thread does my hub have?
Hi, well first off, my bike shop rocks. I went in there to ask them how much it would be to convert my 6-speed bianchi to 9 or 10 speed vs. keep it 6 speed.
The guys in there pull out a simano 600 hub laced to an aero Araya rim and GIVE it to me! Wow, this is the second time getting free parts from these guys. This is Bicycles Inc. in Arlington. Very good shop.
Well, the hub they gave me is a Shimano 600 hub with part number HB-6207. It has a Regina freewheel on it, part number ORO-BX, which I don't want to use, because my bike has Hyperglide on it currently, and I would like to continue using that.
My question is: What threading does this hub have on it? Can I swap the freewheel with the one on my bike now? It is a Shimano MF-Z012 freewheel.
I am thoroughly confused, and nothing on the internet, not even Sheldon Brown has been helpful. So do Shimano hubs always have the same type of threading? I found somewhere that Regina may have French threading???
Please help, and thanks in advance.

Thread pitch should all be fine, go right ahead. Chances are, the hub is English and the Regina is Italian, but the two are quite compatible.

Shimano hubs were typically English thread. French were available in the 1970s, but only by special order and are quite rare. By the time the HB-6207 came out in the mid-1980s, the freewheel hubs were available only in English. However, there is the possibility that the Regina is Italian thread and has been threaded on the hub. Italian and English threading is close enough that they will interchange, but is not recommended for strong riders or that you constantly swap between freewheels with the two thread types.
If the back of the Regina freewheel body has 1 or 3 grooves, it is ISO or English threading repsectively, which is compatible with each other. No grooves indicate italian freewheel threading.

I don't understand why you're so happy with this freewheel hub when your goal is to convert to 9 or 10speed.

This is obviously much cheaper (free) than converting to 10 speed, and so, that is out. Sorry I wasn't clear.
Thanks all for your help!
I am going to try the Regina freewheel without hyperglide and see if there is a huge difference in shifting. If there is not, then I am going to stick with that.

check out the new Shimano 7 speed hyperglide freewheels. They have an 11-28 that I'll be dropping on my Supersport shortly. Wide range, hyperglide shifting, and sheldon says they are the best engineered freewheels yet. Should thread right on. May need to have your friendly LBS redish the wheel, but you go up to 7 speed and for pretty cheap ($20 for the freewheel, less at some internet shops plus whatever your guys charge to redish the wheel.)

Yes, freewheels like this are easy to source, at least for now ... I've picked up a variety of Shimano , Suntour Winner and New Winner, etc., 5-speed and 6-speed, for reasonable prices in the last year, and there seems to be a pretty steady supply on eBay without a lot of bidding competition.
