ELITA ONE Carbon Seat Post 27.2/30.9/31.6mm MTB/Road Biike Carbon Fiber Seatpost Titanium Screws Light 130g Seat Tube

Hi I have two in use a 27.2 and 31.6 mm several thousand miles on each , rain and rough roads. So far so good only suggestion would be at the clamping area use Teflon paste or a good grease on the carbon to carbon interface. I had a little creaking on the 27.2 the Teflon paste worked well never touched it again.
