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.
