My fixed gear bike is a '60 Viking with a Sturmey Archer ASC hub, 44x15 chainwheel and sprocket, and 700c tires. I don't know the precise gearing obtained but it is the range of 59", 71", and 79". That gets me up some pretty steep hills (not exceeding a half-mile in length) and allows a pretty good pace on the flats. Even with drafting though I give up and drop off the line at 30 mph. Track stands are tricky because of slop in the hub as you rock in position.
