TREK MADONE GEN 8 AERO CARBON SEATPOST (190 MM / 20 MM SETBACK) – PERFECT GEOMETRY FOR YOUR RACER
Maximum aerodynamics, outstanding vibration damping, and flawless system integration: The original Trek Madone Gen 8 carbon seatpost (seatmast topper) ergonomically brings your high-end racing bike into absolute top form. As a genuine replacement part, this seatmast guarantees one hundred percent compatibility with all 8th generation Madone SL and SLR models. Made from ultra-light, race-proven OCLV Carbon, the aero-optimized profile seamlessly integrates into the groundbreaking IsoFlow frame design, saving measurable watts in the wind tunnel.
This highly functional **carbon seatpost** has a total length of **190 mm** (long version) and offers ample adjustment range for your perfect saddle height in bike fitting. Thanks to the generous **20 mm setback**, this seatmast allows for a slightly rearward, biomechanically highly efficient pelvic position. This ensures optimal power delivery during long, powerful rides in the saddle and provides additional relief for the core. With a weight of just approx. 127 g, your aero setup remains extremely light.
