Madone SL 6 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 comfortable on the climbs and perched for the attack.

A Shimano 105 Di2 electronic groupset keeps the price down without sacrificing lightning-fast electronic shifting.

Plus, it's topped off with carbon wheels for extra lightweight performance.

Madone Gen 8’s updated IsoFlow technology is even lighter and up to 80% more vertically compliant than before, absorbing road chatter so your customers can ride stronger longer.

Madone Gen 8 is 77 sec/hr faster than Émonda and as fast as the previous Madone* with new Full System Foil aero shapes that redefine what fast looks like. 

*At 200W as a rider system (bike, rider, bottles/cages, and components)

Shimano 105 Di2 utilizes a wireless cockpit paired with a wired connection between a single, seat-tube-stored battery and the front and rear derailleurs, ensuring absolute reliability in all conditions.

Just like Dura-Ace and Ultegra, the 105 Di2 system is highly customizable using Shimano’s E-TUBE PROJECT Cyclist App on your smartphone. With the app, you can set-up your drivetrain just the way you like it, adjusting shift speed, altering the number of shifts per button actuation, and utilizing Synchronized and Semi-Synchro shifting functionality.

You can also pair the system with third party cycling computers such as Garmin and Wahoo, which allow you to monitor gear selection and battery status.

A high-value, high-performance, full-carbon disc brake road wheel packed with all of the aero and performance benefits of a 35mm carbon rim.

  • OCLV Carbon offers an optimized blend of weight, strength, and durability
  • Tubeless Ready (TLR) rims allow for quick transition to tubeless system
  • 35mm depth OCLV Carbon rim (27mm outer, 19.5mm inner width) Grand Strada spokes 24/24, hex alloy nipples
  • Includes TLR rim strip, TLR valve, and traditional rim strip
  • Warrantied for life, no rider weight limit

All Bontrager carbon wheels are warrantied for life for the original purchaser and come with the added protection of Carbon Care. If you damage your wheels while riding in the first two years of ownership, we'll replace them. It’s that easy.

Starting with the rollout of Madone Gen 8, Trek will begin transitioning from a numerical road bike sizing system (i.e. 47 - 62), to an alpha sizing system (i.e. XS - XL)

This new sizing system will consolidate their Madone size options from eight to six while covering a wider range of riders, from smallest to tallest.
