The Elevn Aero Seat Post extender for the Chase Frames with Aero Seat Tube allows you to raise your existing Aero seat post an for post race cool down rides or when cruising around.

Elevn introduces Aero System Shaping in his seat post and clamp into BMX racing. This is to not only to help gain fractions of a second on the track with improved aerodynamics, but the Aero System Shaping also offers a slightly stiffer feel. We know BMX bikes don’t need to go fully aero testing into a wind tunnel, but when races are won or lost by fractions of a second, every advantage will help.
