Alienation Thunderbird Pivotal Seat

A pivotal seat mounts directly to a pivotal-style seat post using a single bolt that passes through the top of the seat. This system is the standard for modern BMX bikes because it is lightweight, secure, and allows you to adjust the seat angle easily.

This seat features dense mid-foam padding, which offers a balance between comfort for sitting and a slim profile that won't get in the way during tricks. While it is designed primarily for BMX riding, the mid-foam provides enough cushion for cruising between spots.

The seat is built for the rigors of BMX, featuring a woven outer material that resists tearing and double-stitched seams to prevent splitting. It is designed to withstand the inevitable impacts and scrapes that come with park or street riding.

Yes, the hollow bolt is a weight-saving feature that removes unnecessary material from the center of the bolt without compromising structural integrity. At 360 grams, the overall design keeps the seat light enough to avoid adding excess weight to your setup.

This seat is compatible with any bike that uses a pivotal seat post. If your current bike uses a railed seat post, you will need to purchase a compatible pivotal post to install this saddle.
