Trek Madone SLR 9 Gen 8 (2025)

It's right for you if...

You eat, sleep and breathe racing, and you want the best road race bike we've ever made. You're looking for a trifecta of aerodynamics, comfort and lightweight in a single bike. You're willing to splurge on things that matter, like our highest-level carbon lay-up, best component spec and any detail that will give you the competitive edge on race day.

The tech you get

An insanely light frame made of our highest-level 900 Series OCLV Carbon with aero tubing and IsoFlow comfort technology, and RSL Aero Bottles and Cages that save watts. Shimano's top road group set – Dura-Ace Di2, for lightning-fast shifts that you can customise. A universal derailleur hanger so you can get a replacement from anywhere. Plus, it's topped off with Bontrager Aeolus RSL 51 tubeless carbon wheels and a Trek Aero RSL one-piece bar/stem.

The final word

The Madone SLR 9 Gen 8 is our lightest, most aerodynamic, top-performing Madone, ready to deliver superbike performance absolutely everywhere. Its crafted with a supremely light 900 Series OCLV Carbon frame for rocketing up climbs, aero tube shaping for slicing through windy descents and IsoFlow comfort tech to keep you feeling good through it all. It's spec'd with the top components and doesn't make any compromises.

 Why you'll love it

• The Revolutionary Full System Foil aero tube shapes redefine what fast looks like and help optimise aerodynamics around the whole bike
• It's crafted from our highest-level 900 Series OCLV carbon, which is mind-bogglingly light and stiff where you need the power, and compliant where you crave comfort
• Carbon wheels keep weight down and performance up, so you can crush climbs and soar down descents
• You get the lightning-fast shifts of Shimano's lightest drivetrain – Dura-Ace Di2
• RSL Aero Bottles and Cages make the whole rider system faster to give you even more aerodynamic gains
• A new Blendr system on the bar/stem makes it easy to add and remove a daytime running light
