Given an affine surjection of polytopes $\pi: P \to Q$, the
Generalized Baues Problem asks whether the poset of all proper
polyhedral subdivisions of $Q$ which are induced by the map $\pi$
has the homotopy type of a sphere. We extend earlier work of the last
two authors on subdivisions of cyclic polytopes to give an affirmative
answer to the problem for the natural surjections between cyclic
polytopes $\pi:C(n,d')\to C(n,d)$ for all $1\leq d
