The problem with most modern frames with horizontal dropouts such as the Surly Crosscheck or Salsa Casseroll is that rear dropout spacing is 130mm or more to permit use of gears, thus limiting the choice of SSFG wheelsets. Although you can often space a ssfg wheel hub from 120mm to 130mm, this puts additional bending stress on the axle that can be an issue if you have heavy loads on the rear of the bike. There are plenty of "track" framesets spaced at 120mm with ample room for fenders and large tires, as well as mounts for fenders and racks. I have a Kilo TT, and the only complaint I have is that it lacks separate fender and rack mounts in the rear.
