Re: Sturmey S2C info
- A year or two ago the person at hubstripping.com had some NOS 2 speed Sachs hubs. I know he had both types of automatics - the two types being the rpm at which they shifted, one for small wheels and the other for large. He may also have had backpedal ones; I forget. I only got one automatic since I already had a couple of bendix backpedal hubs and an old Sturmey Archer S2 non-coaster-brake backpedal 2 speed.
I have one of the Bendix backpedal 2 speeds on my Westfield Compact Super Traveller - the civilian version of the WW2 paratroopers bike, or so I am told (the name is also what I was told; the only label on the bike is Westfield). It works OK here; the bike comes apart in the middle so the lack of cables is a big advantage. I did have the ASC with QR indicator on that bike for a while, but the bike geometry did not work well as fixed.

Hypothetically taking 27" diameter wheels and a commonly available 42T chainwheel and 21T sprocket, I get...scratching on the back of an envelope...two gears of 54" and 74".
