Single bolt seat clamp for frames with seat posts: 27.2mm
P-Guts allow you to use a traditional railed seat (with a hole drilled in it) on a Pivotal post. With some frames being built with the Pivotal top welded on, this is a nice option to have. Also, some people like the ratchet type adjustment of the Pivotal post but want the front to back adjustment and/or flex of a railed seat.
6mm allen bolt Engraved shield logo Will work with any railed seat with a hole drilled in it. S
