Overview
About this bike
Madone SL 6 AXS Gen 8 is a lightweight aero road bike that brings elite racing tech to a lower price point. It offers similar aero benefits to the pricier Madone SLR Gen 8, but with a more economical OCLV 500 Carbon layup and two-piece cockpit with hidden cable routing. It's built to race with geometry that keeps you quick on the sprints yet in control on fast descents. For clean shifts that are fully customizable, it's decked out with SRAM's Rival AXS electronic groupset, topped off with carbon wheels for extra lightweight performance. - Revolutionary Full System Foil aero tube shapes redefine what fast looks like and help optimize aerodynamics around the whole bike - A more economical 500 Series OCLV Carbon frame and new tube shaping shave weight where it matters most to help you fly up climbs - Carbon wheels keep weight down and performance up, so you can crush climbs and soar down descents - You get customizable clean shifting with SRAM's wireless Rival AXS 2x12 groupset - Lightweight, race-focused IsoFlow comfort tech helps you ride stronger longer without sacrificing weight or aerodynamics - This bike comes set up tubeless — a first in Trek performance road history
