Nitto S83 Seatpost 27.2x250 (lightly used)The Nitto S83 is perhaps the finest seatpost ever made. Theres only a few reasons to get any other seatpost, but theyre mainly relegated to color (this only comes in silver or super limited edition black) and size (this only comes in a 27. 2mm diameter normally, if you ask super nicely sometimes we can score it in 26. 8!). So if you have a bike that takes a 26. 8 or 27. 2 seatpost, you are ok with silver or black, and you want the best seatpost going,
