Bianchi Oltre XR4 CV Dura-Ace Di2 Disc Road Bike 2022 With an ultra-modern design comprising state-of-the-art materials, the Bianchi Oltre XR4 CV Dura-Ace Di2 Disc Road Bike promotes a genuinely versatile performance that excels up mountain passes, within furious sprints and during solo breaks. The frameset is made from Countervail (CV) carbon that is unique to Bianchi. This carbon combines a special matrix that infuses a visoelastic material into its weave to markedly reduce road vibrations, increase lateral stiffness and reduce weight. The carbon is sculpted into aerodynamic tube sections to minimise aerodynamic drag, while generous clearance for wider tyres offers the opportunity for extra comfort and compliance. A race-inspired geometry positions the rider perfectly for efficient power transfer, and internal routing keeps the brake hoses completely hidden from the wind. Vision 55 SC wheels feature full carbon, lightweight, 55mm deep aero sculpted rims to guarantee reactivity and consistent momentum. Gear changes are enlisted by the range-topping Shimano Dura-Ace R9200 12-speed setup that shifts flawlessly via its semi-wireless configuration. Stopping duties are charged to the hydraulic disc brakes, also of the Dura-Ace marque, that perform with precision and power whatever the conditions. The build is completed with the one-piece Vision Metron 5D ACR handlebar and stem combination that affords excellent stiffness during out-of-the-saddle efforts.
