Seatpost Identification
 

This seatpost came with a Tommasini that I recently acquired, although I doubt that there is any logical connection between the frame and the post. I don't recognize the style or logo. The frame is approximately late 90s (90 95 12 on the bottom bracket,, but not sure how to interpret those numbers) but had a mix of mostly Shimnano tri-color parts installed. The post is 230mm long excluding the clamp assembly, and weighs about 200gr. including the clamp assembly, which seems pretty respectable. The logo is located on the front of the post, about 4cm from the top, and the 27.2 size is stamped immediately below the logo so all of that is still visible with the seatpost installed.. Unusual 2-bolt design with the smaller, rear-most bolt (actually, more like a headless set-screw) just serving as a rest for the rear of the clamp assembly to adjust the tilt.https://cimg7.ibsrv.net/gimg/bikefor...998c347b2d.jpg

The stamped logo is unfamiliar, but the rest of the post looks like an American Classic:

American Classic Bicycle Seatposts, 2015

Looks like you both nailed it - thanks! I'm guessing that American Classic bought the design after Kingsbery stopped making them. Fairly clean design and nice that the complete clamp assembly is separate from the post in the event a replacement part was needed.
