Yeah, disc brakes make total sense for cyclocross.
If you saw the race today, and the two manimals who led it all day on cantis, not to mention the laceration injuries resulting in the fields of junior men, elite women, and elite men, you'd just suck it up and realize this disc movement is just a marketing hoax.
If you feel you need disc brakes because your family made the great decision of raising you in Trondheim or Fairbanks or Helsinki or Duluth, then yes, commute to your frozen heart's content and use that as your frozen-yet-modulates defense. Otherwise, it has no practicality in elite racing.
Crazy, horrific injuries. Wonder how much Avid and Shimano will donate to UCI this year "for continued improvement on quality and safety" to keep these junk products rolling off the lines?
