The Madone SL 5 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 models, but with a more economical OCLV 500 Carbon lay-up and two-piece cockpit with hidden cable routing. A Shimano 105 group set, alloy handlebars and alloy wheels keeps the price down while still delivering clean mechanical shifting you can trust.

New road bike sizing

We updated our sizing system, consolidating the number of sizes and reducing overlap to make it easier to find the right size for you.

Which gen is right for you?

Choose from the ultra-light, ultra-aero Madone Gen 8, the dedicated lightweight climbing bike Émonda or the dedicated aerodynamic bike with Madone Gen 7.

Behind the bike

Hear from Madone Gen 8’s Senior Aerodynamicist on how we designed the new ultimate race bike.

Made for Madone

Dial your Madone for style and speed with bottles, cages, pedals and more, with Madone-compatible accessories.

The always-on team

Research shows the single most impactful measure you can take to stand out to motorists is to use front and rear Daytime Running Lights. The team uses them on every training ride, any time of day—and they’ve found that these lights truly make a difference.

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 that 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 for longer.

Rooted in racing

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

Adjustable aero cockpit

The Madone Gen 8 features hoods that are narrower than the drops so you can adjust your positioning to prioritise 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

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

New road bike sizing

We updated our sizing system to fit an even wider range of riders while consolidating the number of sizes and reducing overlap to make it easier to find the right size for you.

Shimano 105

With shift technology inherited from mechanical Ultegra and Dura-Ace, Shimano 105 gives you top-shelf shifting at a budget-friendly price. Whether you’re commuting year-round or training for the big race, Shimano 105 is a workhorse drivetrain that won’t hold you back as you grow in the sport.

Don’t forget your pedals

This bike doesn’t come with pedals because you’ll have a better time on your new bike if you choose your own. See the pedal guide to find the best pedals for your riding style. We recommend clipless road pedals for control and efficiency.
