Here, we establish the existence of a number of new bulk insulating states at fractional filling in flat bands with Chern number $C=N>1$, forming in a recently proposed pyrochlore model with strong spin-orbit coupling. In particular, we find compelling evidence for a series of stable states at $\\nu=1/(2N+1)$ for fermions as well as bosonic states at $\\nu=1/(N+1)$.
