At $4,200, the Bianchi Infinito 105 Di2 Bike is the most direct path into the 2026 Infinito platform — the newest and most significantly updated carbon endurance frame Bianchi has built in years. The frame story is the same regardless of build level: a fully integrated carbon chassis and fork that delivers 12 watts of aerodynamic improvement over the previous Infinito, with a taller stack for endurance comfort, longer chainstays for stability at speed, clearance for tires up to 700x40, and a hidden down tube compartment for a multi-tool or wind jacket. All of that is present here, with Shimano 105 Di2 electronic shifting and an honest price.

The Countervail Vibration Cancelling System in the seatpost is the same part on every Infinito regardless of build. Bianchi's updated viscoelastic material — bonded into a full carbon aero-flex seatpost — absorbs road vibration at the contact point while keeping the frame stiff for power transfer. The zero offset on smaller sizes is designed around hip angle optimization for breathing efficiency over long rides. It is not a component that scales with price. You buy the frame, you get the seatpost.
The drivetrain is Shimano 105 Di2 — R7150 derailleurs front and rear, R7170 hydraulic disc brakes and shift-brake levers, a 50/34 crankset with Shimano 105 R7100, and an 11-36 cassette providing a practical range for mixed-terrain riding and sustained climbing. Di2's electronic architecture is the same across the 105, Ultegra, and Dura-Ace tiers: consistent, repeatable shifts actuated by a wired system with a seatpost-integrated battery. There is no power meter on this build.
Where the base Infinito parts ways with the Pro tier is at the wheels and tires. The Bianchi B 30R alloy wheels are a functional, durable foundation — well suited to training miles, rough roads, and the kind of everyday riding this bike is built for. The tires are Pirelli P7 Sport in 700x35, a proven training tire at a width that works well with the Infinito's…
