About this bike
Madone SLR 6 Disc brings the ultimate race bike platform to the next level of performance with road-smoothing Adjustable Top Tube IsoSpeed, a slider on the top tube that allows you to fine-tune the amount of compliance in your frame. An all-new 800 Series OCLV Carbon aero frame, race-worthy parts and wheels, and endless adjustment options make it the right choice for anyone who wants to add more trophies and medals to their collection. It's right for you if... You want our best aero frame, the extra stopping power and tire clearance that come with hydraulic disc brakes, and a workhorse drivetrain that's fully capable of racing but won't quit on your hardest training rides either. The tech you get Our lightest-ever 800 Series OCLV Carbon frame with Kammtail Virtual Foil aerodynamic tube shaping and road-smoothing Adjustable Top Tube IsoSpeed, KVF full carbon disc fork, an adjustable aero bar and stem, a 2x11 Shimano Ultegra drivetrain, Tubeless Ready Bontrager Aeolus Pro 5 Disc wheels, a Madone aero carbon seatmast, and Shimano Ultegra flat-mount hydraulic disc brakes. The final word Our best and lightest Madone frame paired with durable, race-caliber components make this ride your quickest way to the podium. Why you'll love it - 800 Series OCLV Carbon is the lightest laminate we’ve ever made, and it makes 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. - Disc brakes offer better braking performance and extra clearance for wider, more stable tires - A separate bar and stem with an aero carbon faceplate gives you great adjustability without compromising on aerodynamics - The Madone seatpost has an integrated mount for the Bontrager Flare RT tail light
