Madone 4.5 WSD

Gifted with the same performance soul as the vaunted 6 Series Madone, the 4.5 offers the durability and value of a Shimano 105/Ultegra mix drivetrain and the silky-smooth ride of a Bontrager Race Lite carbon fork. With a comfort-proven, Performance Fit platform and the energy-saving ride of our proprietary TCT Carbon, 4 Series bikes are the best handling, best fitting, best styled, and best value in their class.
