The Dual-Position Seatpost currently only fits standard round seatposts that are 27.2mm or larger in diameter. 


The reality is that every model of aero bike has a different shaped seatpost, meaning that it is impossible to create a post that will work with every bike. 


We had hoped to make something for the aero-shaped seatpost crowd, but we do not currently have anything lined up in production.
