De Rosa King XS Dura-Ace 9100 Road Bike. The King XS Dura-Ace 9100 Road Bike is an evolution of De Rosa’s previous King models and offers a lower weight, a cleaner look and a more comfortable ride. This is partly thanks to the relocation of the rear brake caliper to behind the bottom bracket, enabling the removal of the seat stay bridge for increased comfort, yet also maintaining frame performance. The chosen material for the frame is a result of extensive research of composite materials and is composed of an advanced blend of 3 materials, TI1000, TI 800 and XN10 Shimano Dura-Ace 9100 Drivetrain. Shimano’s top-of-the-line Dura-Ace offers easy shifting that’s ultra-sick and its components are lightweight and race-ready. Redesigned hoods on the shifters are ergonomically shaped, and an improved lever stroke reduces the effort required to change gear.
