As per the title, I am wondering what if any negatives there are to using a cyclocross frame on the road?
I will preface this by saying this cyclocross frame to be my primary race frame; including crits and road races.
So elements of stiffness and flex are of concern, but fit is primary.
I am currently riding a Specialized Crux, which fits me perfectly.
I was just wondering what everyone's view is of this. The crux frame is built with the same E5 alloy that they use for the allez which is supposed to be a nice stiff frame. I understand that the forks are different and everything to the road bikes, but the angles of the head tube and seat tube and everything marry up very nicely to how I fit on a frame.
Any and all information is appreciated.

You have clearance for wide tyres though so I would use 28c.
That being said, several people raced (and won) on cross bikes during the past collegiate road season in my conference.
I had it setup with an Apex RD and wide cassette, and tried using it for a hilly route one time - terrible idea. The Apex/cassette were wonderful (90rpms going up a 16% grade...), but descending was a bit unsettling. The geometry didn't feel right (I did not drop the bars down the 2" to match my road bike's drop, and I was definitely not confident going even moderately fast down hills.
That being said, I'm sure that, with time, I would get used to its behaviour and become confident leading it down on a curve at 30+mph.
On the other hand, it is wonderful just riding around the city at a leisurely pace: higher position == more visibility and comfort.

As other said the weight is a bit more but there's plenty if 7kg bikes floating around the pro scene and that's with cross tires.
The geometry will be a little more sluggish in comparison compared to that "snap" you would get from a road bike in a sprint. If I were racing a cross bike in a crit I would definitely try to solo vs take my chances against guys better equipped in a field sprint.

The main difference is weight (although I have some farsports 38mm carbon climchers for on road), the wheelbase is a bit longer and it is heavier.
That said - so far so good!
