Product Highlights


Trek's highest grade carbon makes the frame incredibly light, stunningly responsive and compliant.


Shimano's flagship offering, this 11-speed electronic groupset maximises accuracy and efficiency.


The Madone's Kaamtail frame tube shapes make it one of the world's most aerodynamic road frames.


This top tube design uses an adjustable dampener to improve compliance at the rear of the bike.

Trek Madone SLR 9 Disc Road Bike 2021

Light, stiff and fast, Trek's Madone SLR 9 Disc Road Bike is the ultimate race machine, constructed from the brand's latest carbon fibre - 800 Series OCLV. Engineered to give you the upper hand when it comes to speed and handling, this bike boasts a rich palmarès in the pro peloton, proving its capabilities for every rider at every level. Kammtail Virtual Foil tubing, extensively tested in the wind tunnel and in real-world conditions, is incredibly aerodynamic and, together with the complete integration of all cables and the inclusion of 60mm deep Bontrager Aeolus XXX 6 wheels, reduces drag to an absolute minimum. The frame perfectly balances rigidity, vertical compliance and stability, and incorporates an IsoSpeed decoupler with elastomer into the top tube for additional adjustable compliance that rebounds in a smooth and controlled way. With an H1.5 Fit, your position is dialled in to optimise aerodynamics but will remain comfortable for longer races and rides.

Dura-Ace Di2 is Shimano's flagship electronic groupset, providing lightning-fast shifting that's smooth and precise at just a light touch of the lever. Mid-compact gearing gives you all the ratios you should need, be that for a long alpine climb or a flat-out sprint, and there's a Dura-Ace R9100 Power Meter incorporated into the crank so you can train more efficiently. Braking is just as reliable, with the hydraulic discs creating modulated power in dry and wet conditions, and allowing you to fit wider tyres if preferred. The finishing kit has been designed for its drag-reducing credentials and includes a Madone-specific handlebar, stem and seatpost.


  • 800 Series OCLV Carbon is the lightest laminate Trek has ever made, and it makes the Madone faster on any terrain, in any conditions
  • Adjustable Top Tube IsoSpeed lets you adjust compliance to your preference, and it's damped with an elastomer so it rebounds in a smooth, controlled, stable motion 
  • H1.5 Fit is the sweet-spot geometry of a low aero riding position that's comfortable on long days in the saddle
  • Built for flat-mount disc brakes for extra tyre clearance and all-weather stopping power
  • A separate bar and stem with an aero carbon faceplate gives you great adjustability without compromising on aerodynamics
  • The Shimano Dura-Ace Di2 electronic drivetrain delivers lightning-fast precision shifting
  • Bontrager Aeolus XXX 6, OCLV Carbon, tubeless-ready, 60mm deep wheelset
  • The Madone seatpost has an integrated mount for the Bontrager Flare RT tail light
  • Madone Project One ICON paint schemes make the ultimate racing bike a true piece of artwork
