From the Fyxation site:

"We also made the rear wheel spacing 132.5 to accommodate a road hub or internal gear hub.Want to run a large tire? The Quiver can take up to 700x47c. Need fenders or a rack? The Quiver comes equipped with dual eyelets in the rear dropout and fender eyelet on the fork."

I was wondering when the fixie companies would get wise and do a road bike as cheap or nearly as cheap as a fixie.
It really makes a lot more sense than buying a fixie, the heck with the purists.

With 132.5 spacing you could run road or 29er mtb wheels. The 700x47 tire clearance is a fantastic feature.
I noticed the is a chainstay bridge, that's good. I've had cheap steel frames break which I felt would have been longer lived with a bridge.

The only thing I don't see is braze-ons for downtube shifters but clamp-ons are available.
