No, I wasn't joking. I know about older road frames, they're generally what I prefer to ride myself, but I figured Sturmey/Sunrace would likely be marketing this hub at owners of new frames/bikes as well as vintage/garage sale geeks. As far as I know, aside from single speed mountain bikes, the only new frames being widely produced these days with track ends tend to accept 120mm rear hubs.

Thanks, tcs, for the info about variable OLD's.

The other thing I wonder about is the cog retention system. Does Sturmey Archer have a proprietary spline that is consistant across all of their hubs? I know SA has a great reputation for long term serviceability and parts availability, should I expect to be able to find replacement cogs ten years from now?
