The Madone SLR 6 is a true racing machine that can’t help but be incredibly fast. At its core is a frame made from 800 Series OCLV Carbon with exclusive IsoFlow technology, which provides an impressive aerodynamic advantage, reduces weight, and effectively smooths out road imperfections. This package is complemented by reliable components, such as Shimano's wireless, electronic 105 Di2 12-speed drivetrain.
