Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Disk hub flip flop?

I found this on 63xc.com: http://www.63xc.com/jasom/milldisc.htm. It tells you how to bolt a sprocket onto a disk hub, for a useful fixed gear flip flop. Anyone ever done this? Is it safe? Any idea what the chainline would be? I'm considering doing it on a 9 speed hub, so I can have just one wheel for my 9/SS do-it-all bike (ah, the joys of removable derailer hangers ).

Boone makes a Ti cog to do this. A couple of my friends are running this. Chainline is perfect, quality is nice. See this thread.

Any guess on how small a cog could be bolted on like that? I'm running a 32 tooth front ring and I'd hate to have to get a bigger ring to make it all work.

The one in the picture is a 17t, I'm guessing you can't go much smaller than a 16t. Works for off-road in your situation, but not the asphalt.
