Style
Trek's lightest and fastest road race bikes combined to create Madone Gen 8 - the one true ultimate race bike. Part Emonda. Part Madone. All-out podium-topping performance.

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, but with a more economical OCLV 500 Carbon lay-up 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. A Shimano 105 group set keeps the price down while still delivering clean mechanical shifting you can trust.

Highlights:
- Light as Emonda, fast as Madone, it's the best of both worlds - and the only road race bike you need!
- The Revolutionary Full System Foil aero tube shapes redefine what fast looks like and help optimise 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
- You get clean and reliable shifting without breaking the bank with Shimano's workhorse group set - 12 speed 105
- Lightweight, race-focused IsoFlow comfort tech helps you ride stronger longer without sacrificing weight or aerodynamics




It's right for you if...
You want a featherweight road race bike without top-end race pricing. You're up for racing, club rides or solo spins up winding canyons, and don't want to compromise between climbing efficiency and aerodynamics. You're happy with more economical components that help you get on your dream bike faster.

The tech you get
An ultra-light OCLV 500 Carbon frame with aero tubing and IsoFlow comfort technology. A 2x12 Shimano 105 group set that delivers clean mechanical shifts without the faff of electronic group sets. Tubeless wheels that help fight punctures while reducing rolling resistance, and hydraulic disc brakes.


Details

- The ultimate race bike at the ultimate price
The all-new Madone SL shares all the same revolutionary frame technology as the SLR model, but keeps costs down with more economical 500 Series OCLV Carbon and two-piece handlebar/stem combo. You no longer have to choose between fast and light, sprinting or climbing. With Madone Gen 8, Emonda riders get an even more aerodynamic ride, and Madone fans get an ultra-light bike that helps you climb faster than ever.

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

- T47 BB
A T47 BB gives the ultimate in performance and serviceability. Cables are almost totally hidden, but still route externally to the bars, making service easy.

- Geometry
The Road Race fit means that performance riders of every gender will find a powerful and aerodynamic position on Madone.

- 3S integrated chain keeper
The 3S chain keeper is integrated directly into the bike frame. It's an elegant solution that provides flawless gear shifting even on rough roads and under heavy loads. No more standing on the side of the road, covered in grease, unwedging your dropped chain as competitors race by.

- Blendr Integration
Blendr seamlessly mounts Bontrager computers, Bontrager Ion lights and Garmin and Wahoo computers directly to the handlebars, keeping everything zip tie-free and in its place.
