  In scenarios motivated by string theories, it is possible to have extra
Kaluza-Klein dimensions compactified to rather large magnitudes, leading to
large effects of gravity at scales down to a TeV. The effect of the spin-2
Kaluza-Klein modes on the deep-inelastic cross-section at HERA is investigated.
We find that the data can be used to obtain bounds on the effective low energy
scale, $M_S$.
