Wanted GT or KORE seatpost 27,2mm silver + GT seatpost clamp

[DrmZ]

I'm looking for a seatpost for my GT in silver with 27.2mm diameter.
Would prefer a GT branded post but would take a KORE Lite post, too.

Also looking for a GT seatpost clamp with 28.6mm diameter and preferably with quick release.
Black or silver would work for me.

Is it a steel or aluminium frame you have?
Outer diameter can vary depending on material.
Also, depending on age, older clamps are much harder to find in either 28.6 or 29.8 dia.
31.8 is easier to find but won't fit, obviously.
