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.
