Fork crown/integrated headset question
 

Just purchased a new fork for my cyclocross bike, and didn't take into account that the bike has an integrated, not external, threadless headset. Any issues using a fork that was not designed for an integrated headset? If it helps, this will see race use. I'm assuming there might be, but thought I would throw the question to the forum prior to returning the fork.

My biggest concern is since it will see muddy conditions, there might issues that arise more quickly with the lower bearings. Any insight into this or other issues that I might not be taking into consideration are appreciated.

AFAIK, the only difference between a fork designed for an integrated headset and one that isn't is cosmetic. The integrated fork will have a larger crown race seat so it blends into the lower bearing headtube flair more smoothly. I don't believe there is any structural difference.
