  Astrophysical bounds severely limit the possibility of observing collider
signals of gravity with less than 3 flat extra dimensions. However, small
distortions of the compactified space can lift the masses of the lightest
graviton excitations, evading astrophysical bounds without affecting collider
signals of quantum gravity. Following this procedure we reconsider theories
with one large extra dimension. A slight space warping gives a model which is
safe in the infrared against astrophysical and observational bounds, and which
has the ultraviolet properties of gravity with a single flat extra dimension.
We extend collider studies to the case of one extra dimension, pointing out its
peculiarities. Finally, for a generic number of extra dimensions, we compare
different channels in LHC searches for quantum gravity, introducing an
ultraviolet cutoff as an additional parameter besides the Planck mass.
