Description

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 layup and two-piece cockpit with hidden cable routing. A Shimano 105 groupset, alloy handlebars, and alloy wheels keep the price down while still delivering clean mechanical shifting you can trust.

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.
