I've got that exact seatpost in 27.2X400, and it's really good--looks great and totally solid after 1500 miles. No QC issues whatsoever that I can detect. 263g. I did have a weird issue where the seller sent me one with a different clamp than pictured, one that didn't work with oval rails, but we worked it out.This one is $53, but unknown manufacturer so similar situation to a lot of the carbon stuff out there:
I'm selling mine, however, only because I had to switch to a setback with my new bike. Found a good deal on a NOS 3T Dorico LTD, which I like a lot so far.
