Wicksie: I have indeed looked at the Surly Dingle and things like that. On a side note: How the hell do you order from Freeman?
I have just commuted home on 62gi fixed (on the dave quinn with the track bikes wheels and old crankset), and find myself taking 12 minutes more, but it's not infuriatingly slow by any means. I think what Louis said was right, spinny gears are not as bad as you make out in your head, not in London, anyway.
