It is hard to make CF components lightweight (like on a road bike) while still meeting the minimum structure for CX type workloads.
For reference the Niner full-carbon road/CX fork weighs in at around 600grams. Which is needed because it is rated for Condition 2 riding AKA 6" drops or less. Do that on a lightweight road fork (with half as much mass) and it would break sooner rather than later.
