80's vintage American Classic 26.4mm main seatpost tube, Bare post, no parts. The length with clamps installed will make it around 230mm. This bare post will work with the original series M-6 bolt, the clamp pieces of the early series, and the original tilt screw.
You also need to have the special radiused gold washer that works with the main allen bolt driven by a 5mm allen key.
A great find for AM CLassic fans with the parts. You might need this for one of many vintage framesets with 26.4 seat tubes
This model originally was the Mountain bike version with beefed up tubing. This one has the open cut design with the cap at top, indicates early series made in USA
