  Models with one warped and two unwarped extra dimensions allow for the
solution of a number of open questions in particle physics. They can be used to
solve the hierarchy problem in the same sense as Randall-Sundrum extra
dimensions, they incorporate the Randall-Sundrum approach to flavor, and they
generate a dark matter candidate via Kaluza-Klein parity in the flat extra
dimensions. In this paper, we examine the models AdS_5 x T_2 and AdS_5 x S_2,
deriving the Kaluza-Klein spectrum for fermions propagating in the bulk. While
the toroidal model allows for a chiral zero mode, we find that the positive
curvature of the spherical model disallows all zero modes without further
modifications.
