Good points. In fact, while my dream may be to take a FG on group rides, I'm really just looking for a fast fixed bike to take on longer, mostly solo, rides. On flats, it definitely feels like it takes more effort to maintain a given speed on my fixed vs. road bike.

It sounds like tires may actually make a difference. And since I'm always on pavement, I might try some slicks. Do fenders also significantly slow you down due to weight and wind resistance? I've got a set of full Planet Bikes on there.

Fit wise, it has a top tube 8mm longer, but the saddle-bar drop is pretty similar.

What about the Tricross vs. Wabi frames? Do I get any significant advantages with the Wabi, other than the nice feeling ride of steel.
