The grooves are spaced apart around the periphery so as to correspond with the tines on the barrel nut. The body further has a circumferentially extending channel in the inner surface, spaced from the proximal end so as to receive the tines therein with the barrel nut in the tightened position to allow limited rotation of the body around the barrel relative to the barrel nut until the tines are aligned behind lands between the grooves.

Abstract: A lightweight, adjustable seat clamping assembly for attaching a seat to a bicycle or like cycle comprised of three links assembled together to create three parallel pivotal axes that form a triangular pattern. One link contains the seat post. Another link contains the seat. The third link provides support between the first two. With respect to the seat post, angular position and horizontal clamping offset are adjusted by altering the positions of the three pivotal axes. Horizontal seat position is adjusted by shifting the seat horizontally within the assembly. The assembly can incorporate a calibration scale that assists the rider in determining and remembering the seat's angular position.
