Had a few frame sets made a while back and grabbed a few seat posts at the same time. These 4130 Cr-Mo tubes have been cut to 320mm or 12.5 inches, so slightly longer than many of the brand name seat posts.
Tubing is 22.2mm or 7/8″ outside diameter tubing. It has a 0.065″ wall. This size fits most old school BMX bikes except for some like the PK Ripper and Race Inc RA?? versions that take a 13/16″ size.
There are two seat posts for sale and price below is for one.
