Bianchi Oltre XR4 CV Ultegra Di2 Road Bike 2020
Steeped in history, Bianchi may be one of the oldest bike manufacturers in the world but their Oltre XR4 CV Ultegra Di2 Road Bike shows just how forward-thinking the Italian brand is when it comes to bike design. A frame designed to accommodate mechanical or electric groupsets, this model features Shimano Ultegra Di2 R8050 11-speed components. Gearing comes in the form of a compact 50x34T crankset and an 11-28T cassette.
Alongside this, a Bianchi Oltre seatpost is aerodynamic and has enough adjustability to cater for a range of positions.
Fulcrum Racing 418 wheels have Vittoria Corsa G2.0 Graphene tyres mounted to them for rolling efficiency, while comfort is provided in the form of a Fizik Arione R3 K:ium saddle.
