Madone SLR 6 is a road racing machine that's serious about speed from the second it hits the tarmac. It all starts with an 800 Series OCLV Carbon frame with exclusive IsoFlow technology that adds an aerodynamic advantage, cuts weight, and smooths the road ahead, then is topped with workhorse components, like Shimano's wireless electronic 105 Di2 12-speed drivetrain to handle race day and shifting clean when the goin' gets hard. Plus, it features upgrades that matter, like carbon wheels with a deep rim for even more aerodynamic gains.
