Have you tried loosening the clamps a little, just quarter of a turn should do it.  Have the clamps done up to tight on any pole will result in excessive wear.

The clamps need only to "nip" the section to give enough grip to hold each section tight. If your clamps are adjusted too tight this can make them "stiff".
