Elevn Aero Extender Post

Elevn's Aero System Shaping in its seat post and clamp results in improved aerodynamics, providing fractions of a second of advantage in a BMX race. It also offers a slightly stiffer feel. Though not undergoing wind tunnel testing, the smallest of advantages will benefit racers where races are won or lost by fractions of a second. Available sizes: aero 25.4 x 495mm for Mini, Junior, and Expert frames and aero 27.2 x 495mm for Expert XL and above frames. Length: 495mm with extension of 325mm.
