Trek Madone SL 7 Gen 8 - The First 50 Replica

Available for a limited-time preorder through April 13, 2026 — The First 50 Replica comes with many of the same graphic and storytelling elements as The First 50 ICON, but on the Madone SL 7 Gen 8. This race-ready road bike gives you the best of every world. It balances price and performance with a 500 Series OCLV Carbon frame, aero geometry, and IsoFlow technology. You get a Shimano Ultegra Di2 wireless electronic drivetrain to deliver clean shifts every time, all topped off with carbon wheels and carbon handlebars for lightweight performance.

Our lightest Madone SL Disc ever

New light and fast aero tube shaping paired with light-yet-economical 500 Series OCLV Carbon makes Gen 8 our lightest Madone SL Disc f/s ever and the ideal climbing bike.

Redefines what fast looks like

Revolutionary new Full System Foil aero tube shapes improve airflow over the whole bike while maintaining the lightness climbers crave. Plus, the bike’s entire rider system was meticulously designed and rigorously tested to be faster everywhere.



80% more vertically compliant IsoFlow

We refined our race-focused comfort tech to be lighter and have nearly double the vertical compliance so you can ride stronger longer.

Rooted in racing

Madone SL was informed by feedback from Lidl-Trek's fastest sprinters and climbers.

Adjustable aero cockpit

Madone Gen 8 features hoods that are narrower than the drops so you can adjust your positioning to prioritize aerodynamics or power. Plus, the two-piece design lets you quickly and easily dial in your fit.

Add-on aero bottles to make your whole bike faster

Add-on RSL Aero Bottles and Cages were designed with Madone Full System Foil aero shapes to make the whole rider system even faster.
