Does anyone know where I can buy the above from? I don't really want to use a shim. Has anyone ordered from Litespeed in the States and presumably I would get stung for import duty? Would the UK distributor be able to order one?
Thank you so much for your help!

Welcome to the forum. I have ordered th PMP Ti SB14 seatpost for my OBED.

PMP is a Italian Ti manufacturer, very close to REWEL. The seatpost is a piece of art and it is durable and not much flexy, but gives some Ti-comfort.
The PMP SB14 is the only Ti seatpost I have found in 31.6 mm and 350mm length.
More information can be found here:
