The Madone SLR 6 is a road racing machine that's serious about speed from the second it hits the tarmac. An 800 Series OCLV Carbon frame with exclusive IsoFlow technology adds an aerodynamic advantage, cuts weight and smooths the road ahead. The Madone SLR is built from the ground up with workhorse components, like Shimano's new wireless electronic 105 Di2 12-speed drivetrain, that know how to handle race day and won't quit when the goin' gets hard. Plus, it features upgrades that matter, like carbon wheels with a deep rim for even more aerodynamic gains.
