White industries to Velocity a23, single speed conversion

We all know, if you race cross, you like pain.  Well, going SS will not only save you from replacing expensive shifty bits after one too many crashes into mud but it will give you just a little more pain since clearly you can not get enough if you make it past a race or two.

The White Industries ENO eccentric hubs are the most elegant and durable solution to the question of how to tension your chain on a bike with vertical dropouts when you go single speed.  Throw a WI trials freewheel, DT Competition spokes, Velocity A23 rims and a fixed cog in case you really feel the need for pain and you have one hell of a cross set up.
