Colnago V4 Shimano 105 Di2 Road Bike

The Colnago V4 Shimano 105 Di2 Road Bike combines a monocoque carbon frame with electronic 12-speed shifting and hydraulic disc brakes for performance-focused road riding. Its carbon fork, integrated cable routing and D-shaped carbon seatpost create a clean, refined build, while the compact 50/34T crankset and 11–34T cassette provide a versatile gearing range for climbs and faster riding.

Fulcrum Racing 600 DB tubeless-ready wheels are paired with Pirelli P7 Sport 28mm tyres, with frame clearance for tyres up to a nominal 32mm. A Deda Zero2 DCR alloy handlebar, Colnago SR10 stem and Selle Italia Model X saddle complete the setup, with cockpit dimensions and crank lengths matched to frame size.
