Ah, Sturmey Archer....one of my favorite subjects.

1) Sounds like you have a 1956 alloy AW hub - same ratios as the steel shell AW. 2) The Cyclo clusters seem to be the most popular - they show up on ebay from time to time and I've even seen list members post one for sale occasionally. Some other alternatives are: You can fit two dished SA cogs on a 3-notch driver. Harris Cyclery (and some other shops) carry 3/32nd cogs - Sheldon Brown is a fountain of knowledge about 3-speed hubs. http://www.sheldonbrown.com/harris/sturmey.html Another option is a threaded driver - these also pop-up from time to time on ebay - perhaps someone on the list has one to sell. You might be able to fit two 3/32nd track cogs on the driver - or - thread on a multi-speed freewheel (I believe Sheldon has an article about this on his website). 3 & 5) Gearing is a real personal matter. Some people don't like the large jumps of a AW hub, but I find the ratios excellent for my style of riding. Sheldon has a gear calc for internals: http://sheldonbrown.com/gears/internal.html 4) Servicing 3-speeds is not as daunting as it seems. Again, Sheldon has some good illustrations as well as a complete parts list on his website. If you want, I'll be glad to snail-mail you a photo copy of a Schwinn AW service manual - it has a complete diaganosis section as well as detailed tear-down and rebuild instructions.
