• For what you have in mind, as long as the steerer matches the head tube, you'll be OK, the fork rake is not massively different. A CX fork will have blades about 40-50 mm longer, so if you fit a road fork, the front of your bike will end up a bit lower, but it's a fixed bike, so I assume you don't care too much... on the up side you'll be more aerodynamic...
