Abstract: An aerodynamically shaped seat post fabricated from carbon fiber is mountable to a seat tube by placing left and right bushings within the hollow center of the seat post. These bushings are accessible and engageable to left and right bolts when the desired height of the seat post is reached. In particular, the left and right bolts are fed through left and right holes formed in the seat tube. The seat post has left and right elongate slots which provide access to the bushings, and more particularly, to the threaded holes of the bushings so that the left and right bolts may engage those threaded holes and clamp the left and right sidewalls of the seat post and the left and right sidewalls of the seat tube together, respectively. This seat post mount eliminates stress concentrations to the seat post. Moreover, the seat post is not clamped down with opposed forces placed on the left and right sidewalls of the seat post.
