We find a new class of spiky solutions for closed strings in flat, AdS3 ⊂ AdS5
and R×S2( ⊂ S5)
backgrounds. In the flat case the new solutions turn out to be T-dual configurations of spiky strings
found in []. In the case of solutions living in AdS, we make a semi classical analysis by
taking the large angular momentum limit. The anomalous dimension for these dual spikes is similar to that
for rotating and pulsating circular strings in AdS with angular momentum playing the role of the level number.
This replaces the well known logarithmic dependence for spinning
strings. For the dual spikes living on sphere we find that no large
angular momentum limit exists.
