I have a Strumey 3-speed fixed hub (built onto Rigida Chrima - similar to an Open Sport). You can fit a freewheel to it- but its not really worth it - so its really for fixed only.

Hiho fella. A few points. If your frame has 120 mm spacing, then the dimension you should be concentrating on is the 'OLN' = over lock nut dimension. The axle length, which I reckon are the '170mm, 163mm and 148mm' is secondary to the hub fitting between the fork ends. The OLN of 117mm has a 163 mm long axle (according to the SJS website). I reckon 117 would be fine in a 120 frame.
I commute on a drop bar thin tyred machine with a three speed hub and I reckon they are the best. As I use a large chainring and large rear sprocket, connected via a 1/8" chain, the transmission is ridiculously reliable and long lived. For hard core city commuting I can pretty well outstrip any other machine. Fixed wheel is lovely but crap for getting through bad traffic filled roads. I would never ride fixed in town. But I've never seen another racer on 3 speed.
The s-rf3 is the latest version of the good ol' fashioned AW series, which has been going for decades. I use the AW, but old ones cut from mundane roadster bikes. Unless the old machine has been submerged or really badly abused, the old 3 speed is usually well good enough to rebuild without any need for major servicing. This latest version seems to have an aluminium shell, which is a rare thing in old SA gears. The more usual old steel shell is normally slightly oily on old bikes, so the chrome is good. The main neg though (apart from being 4oz heavier) is that the steel flanges are thinner than aluminium ones, so you need to stack washers under the spoke heads so that they don't break.
So unless you are keen to shell out £90 odd for a bright new shiny hub, just look around for any abandoned old sit up and beg bike with a 3 speed hub and get the rear wheel. If you are unlucky it'll be a 40 spoke, which can be a pain as these rims are rare (but gettable: go for Rigida Sputniks). But any 1970's onwards will be 36 spoke. -

Much appreciated Shortclaud really helpful information there buddy big thank you, and Knowthejo.
If you can put a freewheel on your hub that would be ideal, who knows one day I might want to ride it fixed wheel, am I right in thinking that the free wheel will only be able to screw on a minimal amount of thread just like screwing a freewheel onto a normal fixed wheel hub? -

Hey dude - I think actually its threads are long enough to take almost all the thread of the FW if not all. Its a lovely piece of kit and comes with a bar-end shifter etc. Also 3 SA differing size sprockets. Only issue is, they aint cheap!!
http://www.futurecycles.co.uk/sturmey-archer-3-speed-fixed-gear-hub-s3x-2.html -Well, I just realised I tell a lie. When I got it it was that expensive - but I thin kyou can grab them cheaper these days. I would be looking for about £140 for the wheel with all the kit (still have orginal box etc).
Im away at the mo - but can sort you out pics - or come have a looksee - im in SE4. Back on the 1st.

I have a 1980s AW 3-speed hub built into a silver Mavic Open Sport rim, you can have it for £55 posted. It needs new anti-rotation washers (about a quid or so) but the toggle chain and axle nuts are there. I'm visiting family at the moment but I can post it when I get back home, around the 3rd-4th January. PM me!

Just PM'd you mate
Hi there, I am looking for a wheel built up with a Sturmey Archer 3 speed hub.
Its for my track bike with 120mm spacing, I understand that these hubs come in 170mm, 163mm and 148mm, so re-spacing the hub will need to take place or what ever needs to be done to make it fit!
Alternatively if someone has just a 3 speed hub they are willing to part with I would be happy to take that and then just build a wheel around it.
I believe the hub I am looking for is the S-RF3 version.
Sourcing a 3 speed shifter and the necessary cable should not be a problem, I might even buy the little bits new, just the hub is the main bit I am after at the moment.
But if someone is selling the complete bits to get me rolling that would be amazing.
If you guys think I am going down a lost road fitting a 3 speed hub to my bike please also advise me or suggest other alternatives.
I am having to dish out my own cash after a long frustrating case against the underage chap who decided to take his anger out of my bike went in his favour.
I wont go into detail!
Much appreciated.
PS, I set up a small t-shirt company this winter if anyone is interested!
