It's right for you if...

You want to go really freakin' fast. You know exactly what it's like to be off the front, battling the wind in a solo break, and want all the free speed you can get. You also know a great value when you see it, and appreciate the fit and customization options of a standard bar and stem, and the all-weather stopping power of disc brakes.

The tech you get

A lightweight 500 Series OCLV Carbon frame and fork with Kammtail Virtual Foil tubes that cut through the wind, a road-smoothing IsoSpeed decoupler, a Shimano Ultegra 2x11 groupset, tubeless ready Bontrager Aeolus Comp wheels, hydraulic disc brakes, and an aero handlebar that's compatible with clip-on aero bars.

The final word

You get the free speed, aerodynamic advantage, and superior ride quality of our ultimate race bike at a great value, plus the added ability to mount clip-on aero bars for time trials and triathlons.

  1. 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
  2. All the aero advantages of Madone, plus the added capability to clip on aero bars for triathlons and time trials
  3. Disc brakes offer better braking performance and extra clearance for wider, more stable tires
  4. The Madone seatpost has an integrated mount for the Bontrager Flare RT tail light
  5. Let's be honest: this bike looks awesome, like it's breaking speed records even when it's parked at the café for a post-ride espresso

Sizing & fit

The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
