my gios (my geared road bike) has adjustable vertical drop outs.
IMO they look great but the problem with using them for fixed (on my gios at least) is that they only have about 8mm of adjustment which doesn't give anything like the range i get from the fork ends on my track bike.
There are 4 options (that I know of):
1. vert with tensioner
not really serious is it? leaving the option to go back.
may as well leave the old derailleur on with a short length of cable to set it to the required adjustment. look like crap but cant be much worse than a tensioner.
2. vert with eccentric BB
3. track fork ends.
i saw a "Spot brand" cyclocross frame with fork ends. neat frame
Spot offers the same frame with vertical drop outs and an Eccentric BB - i haven't seen one though.
4. horizontal drop outs.
i just checked the surly site and their "cross check" has horizontal dropouts.
i put horizontal DO on my MTB when i converted it. i am happy with it. i dont know what benefit fork ends would have given me.
for a cyclocross bike, i would lean toward the horizontal drop outs.
